Description of symposia to be held at the IAGA Scientific Assembly in Sopron in 2009

Division I

I01. Planetary Dynamos: theory, models, observation and experiment

Div. 1 and SEDI

MaMagnetic fields are generated by dynamo action in the interiors of the Earth, and the planets, Jupiter, Saturn, Neptune, Uranus, and possibly Mercury. Our current understanding of these natural dynamos relies on theory, computational and analytical modelling, observations and laboratory experiments. Advances in computer hardware and software are improving the numerical modelling of dynamos. Small scale turbulence, which cannot be directly computed, requires sub-grid scale modelling, such as large eddy simulation techniques. Observations, such as the magnetic data from recent Earth satellites, provide important constraints on natural dynamos. Substantial progress is being made in laboratory experiments on magnetic field generation in electrically-conducting fluids. Comparative studies of the natural dynamos with numerical dynamos and laboratory experiments, which typically operate in different parameter regimes, should increase our understanding of the dynamo process in the Earth and other planets.

We call for contributions on all aspects of planetary dynamos: theory, models, observations and experiments. Contributions which improve our understanding of the geodynamo are particularly welcome.

I02. Consequences of ionospheric-magnetospheric processes on magnetotelluric response functions

Divs. I, II, III, and V

Magnetotellurics is a method to image the subsurface electrical conductivity structure through electromagnetic induction, where the source field is provided by natural electromagnetic signals of magnetosphere-inonosphere origin. From some very long (ground observatory) records more or less regular variations of the response function have been observed. If the subsurface is constant, any variation in the response function refer to processes in the source field, e.g. to plasmaphysical processes of the outer environment.

Papers dealing with periodic modulation of electromagnetic response function are sought. Presentations focusing on field observations at low, middle and high latitudes, and on associated ionospheric and magnetospheric sources behaviour are welcome.

I03.
Continental Lithospheric formation and deformation
In honour of Toni Ádám's 80th anniversary

Divs. I and V 1/2 day

What are the processes by which the lithosphere beneath the continents is formed and subsequently deformed, and do these processes result in structures and geometries that can be imaged by electromagnetic and geomagnetic methods? These questions are at the heart of this session, which will explore whether deep-probing electromagnetic data and models of satellite and ground-based magnetic data can give insight into Earth processes, and particularly their secular variation.

I04. Near surface and environmental studies using electromagnetic induction

Div.I

With the development of new technologies, new instruments, and improved data-processing, electromagnetic methods are able to image shallow structures with applications to many environmental problems. Examples include contaminated unconfined aquifers associated with landfills, landslides, seawater intrusion in coastal areas, the detection of cavities, and the detection of sinkholes and caves in karstic areas. Recently, landmines and unexploded ordnance hazard have appeared as other fields where electromagnetic methods can provide useful applications. We would like to invite contributions related to the issues discussed above, including case studies, the development of novel applications of electromagnetic methods in hydrogeophysics, and the joint inversion of electromagnetic data with other geophysical datasets.

I05.  Deep mantle structure imaged by electromagnetic observations using long-period MT, cables and satellites. EM studies in oceans.
In memory of Ulrich Schmucker (1930-2008)

Div. I and ICDC

An increasing number of initiatives have been taken to study the electromagnetic (EM) signature of the Earth’s crust and mantle. These initiatives include both the acquisition of new high quality data obtained at the planet surface and/or from satellite and development of new tools for the analysis and interpretation of EM data and its comparison with other geophysical and geological data. We encourage presentations addressing these and related questions comparing or integrating different geophysical methods and models, with special focus on EM works that synthesize regional and global compilations to increase our understanding of lithospheric - asthenospheric structure and processes behind its formation and evolution, as well as studies related to new developments on deep EM methods. The session is completed with papers about EM studies in the ocean.

I06. Crustal tectonic processes constrained by electromagnetic observations
       In memory of Mark Berdichevsky

Div. I

Study of the crustal processes helps to delineate the natural resources, seismically active zones, geothermal regions etc. The session is devoted to research contribution of electromagnetic studies in resolving structural features of crust ranging from Archean to Recent in age. Recent review paper on EM investigations of the lithosphere in Europe provided an overview of the large-scale EM surveys on a regional scale. We particularly invite such large scale studies. The session also addressed the role of EM in monitoring crustal processes. EM monitoring of seismic and volcanic processes have examined correlation of electrical resistivity models with crustal melting, seismicity, and fault zones. Convener: T. Harinarayana, Magnetotellurics Division, National Geophysics Research Institute, Uppal Road, Hyderabad – 500 007, India; tel: +91 40 23434613; fax: +91 40 23434651; e-mail: thari54@yahoo.com

I07. EM modelling and inversion

Div. I

In all areas of applied geophysics numerical methods are increasingly important. The interpretation of electric and electromagnetic field data is impossible without adequate numerical modeling and inversion codes. Growing computer power and new numerical algorithms propel the methodological development of modeling and inversion techniques Although these techniques are as close to reality as never before, nature still holds a lead due to the multi-scaled complexity of its materials. The boundaries between classical methods as dc resistivity, induction and electromagnetic wave methods dissolve. The physical responses of dielectric permittivity and magnetic permeability mingle with pure inductive processes. Three-dimensionality, topography, complex geometry, anisotropy, large parameter contrasts, discretization and parallelization are just a few key words of current research in the field of simulation. Classical and alternative inversion concepts allowing for smooth or sharp boundaries, parametrization strategies, stochastic approaches for global minimum search, all-at-once approaches, resolution analysis, model appraisal, and sensitivity studies represent current areas of research in the field of inverse problems. Besides pure numerical topics, the presentation of specialized codes for marine, land-based, airborne or any other electromagnetic application are of great interest for practitioners and developers.

Concluding, we invite contributions to all methodological and computational approaches in all areas of electric and electromagnetic methods.

I11. Developments in magnetic anisotropy

Div. I

Conventional AMS measurements have been widely used in studying the magnetic fabric of igneous, sedimentary and metamorphic rocks. This session intends to be a forum for papers dealing with the AMS of any of the mentioned rock types, preferably in combination with a detailed rock-magnetism study and other anisotropies of the magnetic properties, such as the anisotropy of remanence or high field anisotropy. Presentations about the applications of variable AC field amplitude and frequency in studying the anisotropy of the magnetic susceptibility, as a new technique to help the interpretation of anomalous or inverse fabric, are especially welcome

I12. Palaeointensity and archaeointensity – results and their implications, methodological advances, and open issues

Div. I

Records of ancient geomagnetic field intensity variations are being produced at an accelerating rate from igneous, sedimentary, and baked archaeological materials and are being applied to such diverse and exciting topics in geoscience as geodynamo theory, climatology, and mantle convection. All of this in spite of the well-documented difficulties associated with producing reliable measurements which have themselves motivated a rapidly growing number of studies focused on improving the experimental and analytical methodologies. We solicit presentations based on any aspect of palaeointensity (absolute and relative) and archaeointensity determination and particularly welcome contributions which directly address controversial issues associated with either the acquisition of intensity records or their implications for important, interdisciplinary problems.

I13. Paleomagnetic, geomagnetic and rock-magnetic procedures: field tests, instrumentation, statistics

Div. I 1/2 day

The rock and sedimentary record of the Earth magnetic field is based on straightforward principles established since more than fifty years. Nevertheless, continuous research in this field and progressive extension of the paleomagnetic database, progressively opened a “Pandora box” of complex phenomena related to the formation of iron minerals, and the acquisition of a magnetic remanence in weak fields. A deep understanding of these phenomena requires an interdisciplinary approach that spans from pure mathematics, to mineral physics, geochemistry, climatology and biology. Emerging techniques, such as nanoscale magnetic imaging, magnetic tomography of fine particles, single crystal demagnetization, as well as new paleointensity procedures, are now emerging frontiers that will be addressed in this session. Contributions describing novel instrumentation, (geo)magnetic data acquisition and analysis procedures, rock magnetism, paleointensity, and magnetic imaging techniques are welcomed, especially in a combined approach that allows a reliable cross-check of new theories and models.

I14. Geo- and paleo-magnetic data constraints on geodynamo models

Div. I and SEDI

Geodynamo models are becoming increasingly sophisticated and can now be used to elucidate specific processes such as polarity reversal, characteristics of the secular variation, and morphology of the time-averaged field. At the same time paleomagnetic studies are producing more reliable data, in increasing quantities, for the ancient geomagnetic field, and satellites are producing better resolutionin both time and space for the present geomagnetic field. This three-fold advance has allowed combinations of theory and measurement at a level not possible until now.

This session will focus on studies that use dynamo theory to address specific observational characteristics of the geomagnetic field, and those that use observations to constrain dynamo theories. We solicit contributions on observation, interpretation and modelling of geomagnetic variations on all time scales. We particularly welcome contributions featuring dynamo models and theory capable of explaining field reversals and excursions, and the long term behavior of the geomagnetic field.

I15. Rock magnetism: theory, experiments and observations

Div. I

Rock magnetism underpins our interpretation of numerous paleomagnetic and environmental magnetic phenomena, yet there are a number of areas within rock magnetism that are evolving rapidly and may lead to new understandings and applications. This session welcomes contributions to applied and fundamental rock magnetic research from all areas ranging from basic mineral identification to geological interpretation. Both field and laboratory-based studies are encouraged, as well as numerical simulations and theoretical applications. Topics for this session include, but are not limited to, magnetic and non-magnetic mineral identification techniques (e.g., low-temperature magnetometry, Mössbauer spectroscopy, magnetic hysteresis, electron microscopy, etc.), challenges in recovering characteristic remanent magnetisations (ChRMs), paleointensities (both relative and absolute) of the ancient geomagnetic field, magnetic granulometry, identifying pathways and degrees of magnetic mineral alteration, and methods for distinguishing mineral fabrics from induced and remanent magnetic anisotropies.

I16. Environmental magnetism and biomagnetism

Div. I

The magnetic mineral inventory in marine and terrestrial sediments reflects various processes. These may occur before or during sediment deposition ( e.g., weathering of the source material, transport, steady vs. non-equilibrium sedimentation, etc…) or after sediment burial (e.g., sediment mixing, authigenesis, biomineralization, geochemical alteration and dissolution, etc.). Each process can leave a characteristic fingerprint in the magnetic record, which may be obfuscated later on, thereby hampering the deconvolution of the record into the underlying processes. The aim of this session is to provide a platform to discuss recent developments towards establishing robust quantitative magnetic proxy parameters (e.g. for humid/arid conditions, warm/cold climates, high/low productivity, biogenic minerals, redox zonation, etc.), magnetic monitoring of pollution, comparative studies (geochemical vs. magnetic proxy parameters), unmixing models, and theoretical and conceptual models of authigenic/biogenic mineral formation in a wide range of environmental and Earth science applications.

I17. Paleomagnetism and rock magnetism of anomaly source rocks

Divs I and V

Interest in magnetic anomalies has increased in recent years with the observation of large remanent anomalies on Mars, with the upcoming Swarm mission investigating the Earth’s field, and with renewed interest in magnetic signatures of economic mineral deposits. This session invites contributions of paleomagnetic and rock magnetic studies on magnetic anomaly source rocks at all scales, including marine magnetic anomalies and regional and local crustal anomalies.

I18. Open poster session

Div. I

This session is addressed to a broad audience in Geomagnetism, Rock-, Palaeo- and Environmental magnetism. Topics involving magnetic studies of different past and present environments, materials (natural and synthetic) as well as new methods and developments are appreciated. Multi-disciplinary approach involving other physical and chemical methods in addition to magnetic studies is encouraged. Contributions from other fields of natural sciences demonstrating relevance and new ideas for applications in Geomagnetism and Environmental Magnetism are worthwhile. Presentations that do not fit directly into the scope of the other magnetic sessions are also welcome. Although this session comprises only contributions as posters, we encourage authors presenting novel ideas, new interpretations and provocative theories in order to trigger attractive discussions at their poster board, and hence to promote oral communication among the authors and audience.

Division II

II01. Electrodynamical coupling from the troposphere to the magnetosphere related to thunderstorm electrical activity

Div. II

Twenty years ago, a process of “upward” transfer of electrical thunderstorm energy was discovered and named “sprites.” Since then, other forms of electrical energy transport to the upper atmosphere and space, also originating in thunderstorms, have been discovered. They can be broadly classified into different categories: the Transient Luminous Events (TLEs), Terrestrial Gamma-ray Flashes (TGFs), X-ray emissions, etc. They span the distance from the troposphere to the magnetosphere. Satellite observations of thunderstorm-related TLEs, TGFs, X-ray emissions, etc. have demonstrated that they are global phenomena. Thunderstorms can also be the origin of gravity waves, while recent results have also demonstrated that sprites can produce infrasound waves. This session welcomes papers on all the electrodynamical effects of thunderstorms on the upper atmosphere, their interaction with the local medium, chemical effects, generation mechanisms and parent thunderstorms, infrasound and gravity waves, magnetospheric effects, similar processes on other planets, and all types of associated phenomena. At the 2009 IAGA meeting we will celebrate 20 years of sprite research.

II02. New findings concerning the polar summer mesosphere/lower thermosphere/ionosphere region including the role of dusty plasmas

Div. II

The mesosphere/lower thermosphere/ionosphere (MLTI) region is now thought to contain large quantities of charged dust and aerosols. During the cold polar summer, the dust can be responsible for many unusual phenomena, such as noctilucent clouds (NLC) and polar mesospheric summer echoes (PMSE). Recently, there has been a flurry of new measurements and studies concerning the MLTI including the role of the dust and aerosols. This session will concentrate on features of the polar summer mesosphere, including composition, dynamics, including the origin, shape, size, and composition of the particles composing the contained dust. Both recent measurements and theoretical considerations will be highlighted. These considerations will also include such items as event dependence on background conditions, the frequency and global distribution of the induced phenomena, southern hemisphere/northern hemisphere differences, and long- term changes.

II03. Long-term changes in the mesosphere, thermosphere and ionosphere

Div. II

Past two decades have enriched us with a variety of observational data from space, airborne and ground-based platforms on several parameters. The primary goal of this symposium is to discuss the most updated experimental and model results on long-term changes and trends in the stratosphere, mesosphere, thermosphere and ionosphere. The symposium will emphasize the emerging trend signals under Global Change and future predictions. Natural and anthropogenic effects on the Space weather system and processes by which they interact. The relative importance of long term natural and anthropogenic influences with their identification will be addressed. Both contributory and solicited papers are welcome.

II04. Solar and lower atmospheric forcing of the middle atmosphere-ionosphere system

Div. II

The Earth’s atmosphere as a whole (including the ionosphere embedded in the thermosphere) is a coupled system influenced by the solar and magnetosphere processes from above and upward propagating disturbances from below. The coupling processes are crucial to our understanding of climate change drivers and space weather events. The symposium invites observational and modelling studies that address the dynamics of the middle and upper atmosphere with emphasis on chemistry and transport, heat sources and sinks, solar and lower atmospheric forcing and the associated feedback on dynamics. Contributions are sought that focus on atmospheric waves (acoustic-gravity, planetary, tides), wave-wave and wave-mean flow interactions, atmospheric electricity and electrodynamical coupling processes. New results on the mesosphere-lower thermosphere wave seeding (wave penetration and secondary wave generation) of ionospheric disturbances and the solar influence on the vertical propagation condition of the waves in the middle atmosphere are particularly welcome. The Symposium will provide the opportunity to review the current progress in this field and suggest future direction of research.

II05. Energetic particle precipitation into the atmosphere: sources and consequences

Divs II and III

Particle precipitation into the atmosphere is one of the mechanisms for energetic electron loss from the Van Allen radiation belts. This is particularly significant during and after geomagnetic storms, when the loss rate, and the source population, can both increase. This session ismagneto targeted at both ground-based and satellite experimental observations, as well as theoretical investigations, into the precipitation of energetic electrons (>20 keV) into the D-region ionosphere and below. Papers considering the precipitation drivers, the nature of the particle fluxes, or the impact of the precipitation on the ionosphere or atmosphere are welcome.

II06. Equatorial atmosphere-ionosphere interactive processes: vertical and latitudinal coupling and magnetospheric forcing

Divs II and III

The Earth’s equatorial and low-latitude atmosphere-ionosphere system is subject to significant modification due to dynamical and electro-dynamical coupling processes arising from upward transport of energy and momentum by gravity-, tidal- and planetary waves originating from lower heights and extra-tropics, which results in its large zonal, day-to-day and inter-annual variability. Magnetospheric/interplanetary forcing through disturbance electric fields and energy deposition at high latitudes with the consequent coupling to equatorial latitudes represents another important source of variability of the system at different time scales. Important new results from ground based instruments networks, space borne observations and simulation studies on the different coupling processes and sources of variability of the system have been forthcoming in recent years. This symposium will address all aspects of the dynamics, energetics and coupling processes of the atmosphere-ionosphere-system of the latitude region extending from the equator to mid-latitudes. Results are welcome from experimental, theoretical and modelling investigations, and on manifestations of the coupling process through the responses of the system to magnetic storms and upward propagating atmospheric wave disturbances etc. in terms of small and large structures, TEC, winds and waves, temperatures, plasma drifts, electric fields, currents, precursor conditions for equatorial plasma bubble development, anomaly and electrojet variability etc.

II07. Forcing of the middle and high latitude thermosphere from above and below

Div. II

New aspects of thermospheric dynamics can now be studied based on observations from low-Earth orbiting satellites, such as CHAMP and GRACE, carrying sensitive accelerometers on board. From the recorded air drag it is possible to derive the details of mass density and wind distribution on global scale. The dependence of the thermosphere on local time, season and solar flux has clearly be revealed from these observations and can be compared with model predictions. Rather new and unpredicted are the thermospheric features related to geomagnetic field distribution, e.g. air up-welling in the cusp region and equatorial mass anomaly aligned with the dip equator. Another area of ongoing research is the response of the thermosphere to magnetic activity, which is poorly reflected by the models. Only recently the prominent influence of non-migrating tides on the thermospheric dynamics has been realized. In particular, the signatures of the eastward propagating diurnal wave-3, DE3, are strong during large parts of the year. The origin of the DE3 tidal mode is related to processes in thunderstorm clouds in the tropics. Papers are solicited for this session on any of the above or related topics that are of importance for determining the structure and dynamics of the thermosphere. This includes observations or modelling of the thermospheric coupling with magnetosphere, ionosphere or lower atmosphere. Papers announcing new possibilities in T-I research with the upcoming ESA constellation mission SWARM are particularly welcome.

II08. Remote sensing of the plasmasphere, and coupling to the ionosphere

Divs II and III

The dynamics of the plasmasphere plays an important role in Earth's space weather system, and is governed by solar activity. Also the plasmasphere is strongly coupled to the ionosphere by means of electromagnetic fields and currents. The plasmasphere forms the cold plasma background for the overlapping 'warm' (ring current) and 'hot' (radiation belts) regions and its plasma distribution is a fundamental parameter for the description and modelling of various physical processes in these regions. This session focuses on various remote-sensing techniques: active and passive ground-based measurements using ULF-ELF-VLF electromagnetic waves as well as satellite-based methods including radio sounding and imaging. Also included are the coupling processes related to cold plasma density.

Division III

III01. Magnetopause and magnetosheath processes: reconnection, diffusion and boundary dynamics

Div. III

The magnetopause and its boundary layers are the prime sites of mass, momentum and energy transfer from the solar wind into the magnetosphere. Understanding the physics of these processes is central to magnetospheric physics. Observations of these regions are continuously ongoing owing to several dedicated spacecraft missions. Space data are further supported by observations from ground based observatories. New progresses in simulations (MHD, hybrid and kinetic) and theoretical knowledge allow the physics of reconnection and boundary layer processes to be elucidated as never before. This session invites contributions on a wide range of magnetopause-related topics, including observations of the structure of the magnetopause current layer, its boundary layers and their transient variations, the signatures of the various forms of plasma interactions, such as magnetic reconnection, and their relevance to solar wind-magnetosphere coupling. The basic physics of reconnection, plasma diffusion and boundary layer formation at the magnetopause, as well as the magnetosheath processes that influence magnetopause dynamics are highly relevant.

III02. Advances in substorm research from multi-point observations in the magnetosphere

Div. III

Substorm research has reached a new era with recent advances in the multi-point observational capabilities in the magnetosphere and simultaneous ground-based observations. THEMIS’s multi-point observations allow us to study the interplay between the midtail and inner magnetospheric substorm processes covering key regions of energy transport and dissipation region simultaneously. Cluster local multi-point observations allow us to measure local instabilities and obtain local properties of the propagation of the current sheet disturbances. Combining THEMIS, Cluster, and other spacecraft at geosynchronous, low-altitude, solar wind, and mid/near tail region, enables studies such as evolution of phenomena along field lines and large-scale solar wind-magnetotail interaction. Comparisons with advanced modelling, specific to individual events, is expected to help bring such observations in a proper physical context. This session is devoted to multi-point observations and relevant modeling studies on substorms. We also solicit papers dealing with new analysis techniques determining propagation of the substorm disturbance using multi-point data in space and on the ground.

III03. Magnetosphere-ionosphere interactions and auroral processes

Divs III and II

Magnetosphere-ionosphere coupling entails the transport of electromagnetic power, particle energy, and mass between the ionosphere-thermosphere and the magnetosphere, and feedback between these regions. The electrodynamic response of the system gives rise to convection, the flow of electrical currents within the system, and dissipation of electromagnetic power, especially in the ionosphere. The inertial interaction involves redistribution of mass and momentum throughout the coupled system, which regulates the ring current, local plasma instabilities, and magnetic reconnection. We now recognize that the electrodynamic response is strongly influenced by the inertial response and vice versa, and that a comprehensive analysis of the coupling requires a unified approach. Moreover, the coupling spans low to high latitudes during periods of strong solar wind forcing. This symposium invites papers on observations, theory, simulation and modeling covering a broad range of topics: How are magnetospheric dynamics modified by M-I coupling, and how does the coupling influence the state of the ionospheric plasma and conductivity? What are the processes involved in plasma inflow/outflow, under what conditions do they occur, and how do they couple the magnetosphere and ionosphere? What role do waves and plasma instabilities play in scale-interactive M-I coupling? How does the M-I interaction mediate cross-latitude coupling? How are these processes manifested in auroral precipitation?

III04. New perspectives of the magnetosphere-ionosphere system from global models, synoptic observations, and data assimilation

Divs III and II

Increasingly sophisticated global models and new developments in ground-based and space-borne observational capabilities have contributed greatly to the understanding of the magnetosphere-ionosphere system. Comparisons of numerical simulations from global models with observations from multiple platforms provide a means to test and improve our current understanding of the physical processes pertained to this coupled system. Papers on comparative modeling studies and ground- and space-based multi-instrument observations of global and mesoscale phenomena of the magnetosphere and ionosphere are solicited. Papers that focus on new numerical techniques and data assimilation methods to reveal new features of the magnetosphere-ionosphere system are particularly suitable to this session.

III05. The plasma sheet - ionosphere, a coupled system: Sinks, sources, transport and the role of Region 2 currents

Divs III and II

Observations, modeling, and theory have now reached the point where the plasma sheet and its coupling to the ionosphere can be considered as a whole, rather than treated as separate issues within ionosphere or plasma sheet physics. Therefore, this is now a topic requiring participation from both Division II and Division III. The plasma sheet is formed from particles entering directly and indirectly from the ionosphere and solar wind. The structure and asymmetry of its pressure, temperature, density, and entropy are determined by the particle entry, transport, and loss processes. All these processes are in turn strongly affected by the electrodynamical coupling with the ionosphere. The plasma sheet dynamics, in particular through the Region 2 coupling currents, strongly affects the ionosphere via particle precipitation and Joule heating. Furthermore, the Region 2 currents cause strong modifications of the global ionospheric electric field distribution, at middle latitudes by shielding and penetrating electric fields, at higher latitudes supporting the SAPS, and in the auroral region causing the Harang electric field reversal. Papers are solicited for this session on any of the above or related topics that are of importance to determining the formation of the plasma sheet (sources and losses), its structure and dynamics and/or the effects electrodynamical coupling has on ionospheric and magnetospheric processes. Papers dealing with the system as a whole or with a near-Earth manifestation of the coupling processes are also appropriate.

III06. Techniques and instrumentation in space plasma physics

Div. III

Space and ground based instrumentation has shown significant advances in technology in recent years. These developments enable a new generation both of measurements and of data acquisition and logistical support for space and ground based instrumentation. Not only have advances been made to improve performance of individual instruments, for example, space based imagers and sensors but also in distributed space and ground based systems to enable improved reliability and autonomy enabling large networks of sensors. New techniques in numerical simulation, operation and analysis of data have been developed to take full advantage of the broad range of measurements provided. This session invites papers describing instrument technologies and developments applied to space physics including both space and ground based as well as papers describing new techniques of measurement, data analysis, calibration and instrument operations not already covered by the other sessions.

III07. Wave and particle dynamics in the ring current and radiation belts/geomagnetic storms

Div. III

Recent progress in the understanding of radiation-belt energization and loss processes, as well as ring-current build-up and decay, has shown that the system is highly variable, and relies on a variety of different waves and other transient phenomena to couple the dynamic processes occurring in the inner magnetosphere. Multiple energization and loss process occur simultaneously, over a variety of spatial scales ranging from microscopic wave-particle interactions, to global-scale interactions, and a variety of temporal scales, from milliseconds to hours. In this session, we will focus on the dynamical behavior of radiation-belt and ring-current particles, the global variability and coupling to the inner magnetosphere, and the nature and spatiotemporal distribution of the underlying waves that control this behavior. In particular we seek contributions demonstrating the spatiotemporal distribution of various waves, including electromagnetic ion cyclotron (EMIC) and whistler mode chorus wave activity, magnetosonic, ECH and other; the role of the ring current in global magnetopause losses due to the inflation of the geomagnetic field; and when ultra low frequency (ULF) waves are efficient in energizing radiation belt particles. Future directions and needs for the field will be captured for future meetings (and possible for a special publication issue if so decided) by holding a panel discussion at the end of the session.

III08. Other magnetospheric worlds

Div. III

This session will focus on a comparative view of planetary magnetospheres and their interactions with satellites and rings. With global data from orbiters of both Jupiter and Saturn in hand, it is now topical to consider these and other globally magnetized planets using a comparative approach. Potential subjects of comparison include magnetic fields and current systems, planetary and satellite ionospheres, magnetospheric interactions with satellites, sources of charged particles (planet, satellite or solar wind), their energization and loss, and system periodicities. Analyses and/or modeling of data obtained in situ or remotely are welcome as are simulations. Magnetospheres of the outer planets, Mercury, and the satellite Ganymede are all within the scope of this session. An example of the spirit of this session is comparing the various periodicities that occur at Jupiter and Saturn and understanding their similarities and differences. This will lead to more general predictions about other rapidly rotating magnetospheres.

III09. Conjugate and inter-hemispheric studies of polar geophysical phenomena: Results from the International Polar and Heliophysical Years (IPY/IHY)

Divs III and II

We invite contributions from space- and ground-based observations, modelling and theory relating to the similarities and differences between the upper atmospheres of the two polar regions, and on the coupling and mapping between the magnetosphere and ionosphere. Inter-hemispheric symmetries provide stringent tests for models and theories of the coupled magnetosphere-ionosphere-thermosphere system. To this end, the IPY/IHY has provided unprecedented ground-based instrumentation in both hemispheres and in space, including the Themis and Cluster spacecraft missions and their associated ground-based support by optical, magnetometer and riometer arrays, incoherent and coherent radars (AMISR, EISCAT, SuperDARN) and much more. To deliver the full potential of this opportunity requires improved knowledge and understanding of the relationship between the magnetosphere and ionosphere and thermosphere, particularly the magnetic conjugacy.

III10. ULF Waves as magnetospheric probes

Div. III

ULF waves, ranging from ion cyclotron waves to MHD waves, can provide valuable diagnostics of the space environment, such as the mass density distribution, the ion composition, and the location of boundary regions. The timing of their occurrence also provides early signals of various dynamical processes such as the propagation of solar wind-driven sudden impulses, substorm onsets, and the enhancement of radiation belt particle fluxes. This session solicits papers that address recent progress in theoretical and/or observational ULF wave studies. Studies of the basic physics of magnetospheric waves associated with any kind of ion motions in either terrestrial or planetary magnetospheres are welcome. Investigations of the role of ULF waves as magnetospheric probes are particularly encouraged; these include the subjects of magnetoseismology, heavy ion mass loading, and new ULF wave indices.

IV01: New solar and interplanetary results

Div.IV
Continuous observations from solar and heliospheric missions have been advancing our knowledge of the physical and dynamical properties of the Sun and the solar wind. These observations, along with theory and models, continue to advance and pose challenges on our understanding of the responsible physical processes. This session invites contributions covering new results from observations from space and ground-based observatories, theory and modeling of different aspects of the Sun and the heliosphere, including its interior, extended atmospheres and the solar wind. This session is aimed at stimulating exchange and promoting discussion on the recent developments derived from observations and latest research in the field.

IV02. From micro- to macro-scales in the heliosphere and magnetospheres

Divs IV, III and II

The NRC Panel Report on Theory, Modeling, and Data Exploration identified “coupling complexity” as a central challenge facing the further development of modeling and simulation in space physics over the next decade. Here, coupling complexity refers to the class of problems or systems that consist of significantly different scales, regions, or particle populations, and for which more than one set of defining equations or concepts is necessary to understand the system. Coupling complexity is very well represented by physical processes occurring throughout the heliosphere and magnetosphere. In the far outer heliosphere, such processes may be identified within that part of the heliosphere whose properties are determined by the solar wind interaction with the local interstellar medium, and especially the coupling of neutral interstellar hydrogen to the plasma. Other problems involve the direct coupling of plasma kinetic to macroscopic processes. For example the understanding of reconnection has taken significant strides forward with the coupling of kinetic physics to the more traditionally understood MHD models, as has our understanding of collisionless shock waves. Another well studied example is particle acceleration in numerous different environments. Such examples abound throughout heliospheric and magnetospheric physics and the goal of this symposium is to explore the common elements across sets of problems that directly incorporate kinetic physics into macroscopic models, either through direct simulations or using transport equation processes.

IV03. Universal heliophysical processes

Divs IV, II and III

The study of the physical space directly influenced by Sun's mass and electromagnetic emissions has been greatly enhanced since the dawn of the space era half a century ago. This space, now known as the heliospace, serves as a great laboratory to study numerous physical processes, thanks to the vast array of ground and space-based instruments that measure various physical quantities. The observational capabilities collectively form the Great Observatory to make scientific investigations not envisioned by individual instrument teams. The International Heliosphysical Year (IHY) program has been promoting scientific investigations on the universality of physical processes such as discontinuities including shocks, particle acceleration, dynamo, magnetic reconnection, magnetic flux ropes, plasma-neutral matter interactions, turbulence, among others. The session will also consider discussion on the solar-cycle variations in the heliosphere and how it is related to the solar dynamo. This session will highlight scientific investigations on these and related topics and showcase the knowledge gained since the birth of Space Science as discipline in 1957. The session will feature several invited reviews by leading experts as well as contributed talks and posters focusing on observations, theory and modeling of the universal heliophysical processes.

IV04. Advances in coordinated Sun-Earth system science through CAWSES and ILWS

Divs IV, II and III

Recent observational advances have allowed us to study the changing Sun with unprecedented detail. Many dominant research topics have become broader as we seek to connect changes at the Sun and of the Heliosphere to changes in the Earth's magnetosphere and atmosphere through a deeper understanding of the physics obtained from interdisciplinary approaches to problems. The challenge of conducting interdisciplinary research in a plasma system as large and complex as one sitting between the Sun and Earth within the heliosphere, which is itself embedded in the interstellar medium, demands long-term, carefully coordinated international cooperation. In response to this need, the Climate and Weather of the Sun-Earth System (CAWSES) and International Living With a Star (ILWS) programs were created. Complementary in their nature and goals, the two programs combine resources from the national and international communities to both advance the state of our knowledge and coordinate and plan Sun-Earth System research missions of the present and future. For this session, contributions on the research highlights from the CAWSES and ILWS programs related to space weather and space climate, including external forcing of the terrestrial climate and the atmospheric response will be solicited and key research challenges for the next five years will be discussed.

IV05: Neutral-plasma interactions for planets, moons, asteroids, and comets

Divs IV and III

This session will be a forum for presenting recent progress in the space plasma physics of solar system bodies without measurable dynamo magnetic field. The interaction of Mars with the solar wind is mainly of the atmospheric type like Venus but with strong modifications of the local ionospheric structure by the crustal fields. Their exosphere makes these planets also share common physical processes with comets. The interaction of Titan with the fast co-rotating plasma inside the magnetosphere of Saturn is another example of such interaction in a different parameter range. The session will be in particular devoted to recent results from Mars Express, Venus Express, and from Cassini around Saturn’s moons including Titan, Enceladus, Rhea and others. Paper relating to Rosetta's Mars and asteroid flybys are also encouraged. Numerous open issues include upstream waves, plasma boundaries and their dynamics, atmospheric and ionospheric escape, influence of Martian crustal fields, etc. Recent results in data analysis and theoretical results, including numerical simulations are encouraged. Papers related to forthcoming space missions (including Rosetta at its comet target and New Horizons) or other future projects are also welcome.

V01. Connecting space and ground-based magnetic data for scientific benefit

Div. V

In the early 21st century continuing advances in observatory practice, ongoing surveys, and unprecedented continuous monitoring by satellite missions present a wealth of geomagnetic data. Each type of observation has different advantages in terms of spatial and temporal coverage, amplitudes of the various sources recorded, and measurement accuracy. In order that maximum scientific benefit is extracted, strategies for combining these diverse data classes are required. Contributions are solicited describing how ground and space-based geomagnetic data might be effectively combined to improve scientific knowledge of the terrestrial magnetic field and its space environment. We welcome papers dealing with topics including the core-field, lithospheric field and induction effects as well as those studying ionospheric or magnetospheric current systems and solar-terrestrial interactions.

V03. Geomagnetic jerks and rapid core field variations

Divs V and I , SEDI

Despite some decades of studying geomagnetic jerks and some progress in understanding this phenomena, some of their characteristics are still in question. The session aims at discussing recent advances of our knowledge on the present state and recent evolution of the Earth's core. We welcome all contributions that open new ways to make inferences on this aspect of core dynamics. Improved combination and analysis of ground and satellite data may help us to make inferences on rapid temporal changes of the core field, from monthly to decadal scales. Comparison of flows within the liquid core with other geophysical and planetary parameters may also be very useful. Geodynamo models, both numerical and experimental, showing short-term variations would be particularly appropriate.

V04. Application, history and evolution of geomagnetic indices

Div. V 1 day

The first continuous recordings at magnetic observatories revealed the high morphological complexity and variability of the geomagnetic field transient variations. It was then discovered that the degree of smoothness of observed magnetic variations significantly change from one day to the other. The first geomagnetic indices thus aimed at characterizing the degree of disturbance of geomagnetic variations observed during a UT day. Two milestones mark the history of geomagnetic indices. The first one is the introduction by Bartels, Mayaud, and Sugiura of geomagnetic indices making it possible to achieve a quantitative monitoring of the various components of geomagnetic activity. The second one is the ongoing digital revolution that began at the turn of the millennium with the massive development of facilities for the acquisition and dissemination of digital magnetic data. For decades, geomagnetic indices proved to be efficient tools in Earth’s magnetospheric and ionospheric dynamics, and still they do. In particular, geomagnetic indices are key data for Space Weather investigations. Recently, geomagnetic indices have also been used to study the long-term development of the Sun and the solar wind. These studies form an essential part of Space Climate. This session aims at revisiting the history of geomagnetic indices, in particular as a tribute to the fathers of modern geomagnetic indices. It also aims at making a panorama of the present situation in the field of geomagnetic indices: already proposed indices that take advantage of facilities of the digital era; user needs and scientific challenges; which indices for the future?

During the last years, the determination of magnetic fields has been improved thanks to the amount of available data from the Earth's surface to the satellite altitudes. Concerted international efforts to compile and publish existing data, like the World Digital Magnetic Anomaly Map project, represented a key motivation for merging airborne and satellite data. These improvements were also possible thanks to the development of new modelling techniques that were prompted by present and forthcoming satellite missions. This abundance of data offers unprecedented possibilities, as well as new challenges, to model the magnetic field at very various spatial scales.

In this session, we invite contributions on all topics related to high resolution mapping and modelling of the magnetic field with a special focus on its lithospheric part using satellite, aeromagnetic and ground magnetic datasets (individually or jointly). We particularly welcome contributions that interpret high resolution spatial modelling and their physical processes at various altitudes.

V06. Tectonic interpretation of satellite, air-borne, ground and marine geomagnetic data

Div. V

The multitude of geomagnetic data available from satellite, ship- and air-borne, and ground observations are now available for geological and tectonic interpretation of the structure, composition and dynamics of the Earth's crust. Recently, much of this available data were combined together to derive the first ever World Digital Magnetic Anomaly Map (WDMAM) and is available to the geomagnetic community in digital form. We solicit contributions relating to the modelling and interpretational studies of any or a combination of the available geomagnetic data. We also invite papers relating to the interpretation of WDMAM map and new modelling strategies being developed for newer versions.
*Papers concerning high-resolution magnetic surveys especially in active tectonic environments are also welcome.*

V07. Results from the decade of geopotential research and future prospects

Div. V

The 'Decade of Geopotential' Research, inaugurated with the launch of Ørsted in 1999, and continuing with CHAMP, is an international effort to promote and coordinate a continuous monitoring of the geopotential (magnetic and gravity) field variability in the near-Earth environment. This year will mark the end of the Decade, and this session is intended both as a retrospective on the accomplishments to date from the high quality data returned from several near-Earth satellites, and an opportunity to look forward to future geopotential field missions such as the three-satellite constellation mission Swarm, scheduled for launch in 2011. Combined with ground based data, the new data has opened numerous opportunities for studies ranging from core flow, mantle conductivity, lithospheric composition and ocean flow to the dynamics of ionospheric and magnetospheric currents. Contributions to these topics and the new satellite missions are solicited for this session.

DC01. Atmospheric coupling processes in the equatorial region

ICDC

Convective processes occurring in the equatorial atmosphere play important roles in the various upper layers of the atmosphere owing to a spectrum of waves they generate at lower levels. A variety of field experiments conducted over Indonesia, India and Brazil has demonstrated the role of tropical convection in the dynamical coupling of atmospheric and ionospheric regions over the tropics. Radio occultation experiments performed on LEO satellites have yielded useful information on tropospheric and stratospheric gravity waves originating from various sources. A number of rocket experiments performed in India have led to quantification of gravity wave contributions to the middle atmospheric SAO and QBO. GCMs have begun to address gravity wave effects by resolving them in high spatial and temporal scales. This symposium aims to address the recent advances made in our understanding of the generation and propagation characteristics of small-, intermediate-scale and large-scale wave motions generated in the lower and middle atmosphere. Papers that deal with electrical processes of lower atmospheric origin that produce noticeable transient effects in the mesosphere are also solicited.

DC02. Low latitude ionosphere-thermosphere system in quiet and magnetically disturbed periods

ICDC and Div. II

Sources that contribute to the day-to-day variability of the low latitude ionosphere-thermosphere system during quiet periods need to be identified in order to quantify changes in the low latitude ionosphere and thermosphere, which arise due to magnetic activity. Further, the roles of promptly penetrating and disturbance dynamo electric fields in the low latitude ionosphere are yet to be understood. This session seeks papers that present new results on the variability of the low latitude ionosphere-thermosphere system during quiet periods; observations of the effects of magnetic activity on low latitude ionosphere/thermosphere, and modeling of the associated physical processes. In particular, case studies from different longitude regions are encouraged.
