Session Title: MG13 “Exploring and modelling the geomagnetic field”

Session scope:

The presence of three magnetic field satellites (Oersted, CHAMP and SAC-C)
simultaneously in orbit at different altitudes and inclinations offers an
unheralded opportunity to resolve not only the core and crustal fields, but
at the same time the contributions from ionospheric, magnetospheric and
electromagnetically induced sources, enabling a true field separation. This
will allow mapping of the geomagnetic field at unprecedented resolution and
accuracy, and will provide a test case for even more accurate mapping
proposed with future satellite constellation missions like “swarm.”
Observatory data will also play an important role in this concert. They
provide a long-term record of the geomagnetic field and are of particular
importance for monitoring the temporal variation of internal and external
components.

In this session, we solicit contributions that explore and model the
geomagnetic field, with an emphasis on analyses of data from multiple
ground- and space-based instruments, and on the combination of data with
physical models. Topics to be addressed includes the geodynamo, core and
lithospheric fields, ionospheric/magnetospheric currents and induction
studies. We are encouraging contributions on low-latitude ionospheric
phenomena, which were only sparsely sampled in previous satellite missions.
Our aim is to bring together scientists working on ionospheric/magnetospheric
current systems with those working on internal magnetic fields. Only in a
joint effort it will be possible to utilise the full information contained
in the observations.

Session ST7 : The solar interior

Rationale:

In recent years significant advances have been made in both theoretical
and observational studies of the solar interior: large and small-scale
motions such as global solar oscillations and waves, solar dynamo and
rotation, convection-dynamics and turbulence, and the coupling mechanisms
of the solar interior-exterior regions of the Sun.

Specialized studies of the solar interior and the solar atmosphere and
heliosphere have to a large extent proceeded separately, and it is timely
with e.g. developments in local helioseismology to encourage exchange and
collaboration between those studying the interior and those studying the
solar atmosphere and heliosphere.

The purpose of the present one-day session [most probably on Friday, 11
April 2003] is to facilitate such interchange and communication between
researchers, as well as informing the wider EGS/AGU research community
about our increasingly detailed and fundamental understanding of the
physics of the solar interior.

The selection of invited speakers will concentrate on the researchers
currently most active in the field. There will be invited and contributed
oral presentations and posters. Post-doctoral scientists, fresh
faculty-position scientists and postgraduate students are especially
encouraged to present their work.

4. Call for abstracts for 2003 EGS-AGU-EUG Joint Assembly Session ST13 on
“The Relationship Between Global ULF Wave Modes, Sources, Plasma
Gradients and Acceleration Processes”
————————————————————————-
From: Robert Rankin

Global and discrete mode ULF pulsations (f ~ few mHz) can arise from a
variety of sources that include internally excited field-line resonances,
wave-particle interactions, and various magnetosphere solar wind
interactions. Observations of discrete frequency oscillations have lead to
the development of various models, including magnetospheric cavity and
wave-guide models, in which the magnetosphere rings at frequencies
determined solely by its internal properties – such as field line topology
and mass density distribution. Recent observations have also shown that the
solar wind can sometimes contain these same discrete frequencies.

The objective of this session is to present new insights into sources of
global and discrete mode ULF pulsations, to understand their global
characteristics (frequency distribution, UT time dependence, etc), and how
they drive processes that energize various particles precipitating into the
auroral zone. Suggested topics include: 1) Internal sources of ULF waves;
2) Observations and theoretical understanding of magnetospheric cavity-mode
and discrete frequency oscillations (f=0.5, 0.8, 1.3, 1.9, 2.6 mHz); 3) The
solar wind as a direct-driver of discrete oscillations; 4) Indirect
coupling of solar-wind energy into ULF waves (e.g., Kelvin-Helmholtz);
5) auroral acceleration processes in discrete mode ULF pulsations. Although
the session is equally weighted against theory (including computer
simulation) and observations, the organizers of this session encourage
submissions that address specific satellite and ground-based observations.

ST17 Ionosphere, Thermosphere, and Magnetosphere Coupling: New insight
from the TIMED era

Convenor: Mark Lester
Co-Convenors: Phil Anderson, Kenneth Moe

The flow of energy through the solar wind-magnetosphere-ionosphere-atmosphere
system is extremely complex. Broadening our understanding of the processes
which control this energy flow requires considerable experimental and
theoretical efforts. The TIMED mission will provide detailed remote sensing
observations of the ionosphere, thermosphere and mesosphere at a range of
latitudes. In addition, existing magnetospheric missions such as Polar and
Cluster will provide experimental data on the inputs of energy to the
ionosphere, while other spacecraft, such as DMSP, can provide detailed in
situ measurements in support of the remote sensing observations.
Ground-based observations from networks of radars, magnetometers and optical
instrumentation will provide additional contextual information. Thus, as we
enter the TIMED era, we can expect a range of experimental results to provide
further impetus to theoretical and modelling work. This session is devoted
to new observations and modeling results which will stimulate our
understanding of how energy flows from the magnetosphere into the ionosphere
and hence the thermosphere and mesosphere. Papers investigating this chain
of events are welcomed.

Deadline for abstracts is 15 January 2003

Session ST23.03
Data Assimilation for the
Ionosphere-Thermosphere-Magnetosphere System and
the Use of Data-Based
Solar-Terrestrial Models

Over the past decade, data assimilation models have become a dominant tool
for specifications and forecasts in meteorology and oceanography. However,
in space physics these models are only emerging, largely due to the lack of
suitable data to be ingested in such models in the past. However, with the
significant increase in the number of data that will become available over
the next decade, data assimilation will provide a powerful technique toward
an improved specification and forecast of the space environment.
Papers
dealing with data sources, data quality issues, and data assimilation
models as well as the use of these models for specific applications are
welcome.

(schunk@cc.usu.edu), V. Papitashvili (papita@umich.edu), and D. Bilitza

Dear Colleagues

We would like to invite you to participate in the Radar Technique session
at the upcoming 2003 IEEE AP-S and USNC/URSI National Radio Science Meeting
to be held 20-29 June 2003 at the Ohio State University in Columbus, Ohio.

In this session we hope for the ionospheric radar community to share its
recent developments to advance the state of the art of radar practice,
including incoherent scatter, coherent scatter, and ionosondes, as well as
related radio instruments such as GPS TEC tomography and riometry.
Techniques for mitigating interference are welcome, as are advances in the
speed or accuracy of parameter estimation and numerical inversion.
