IDV01 Geomagnetism and geospace climatology (Divisions
V and III)
Long-term variations in the magnetic environment of the Earth due,
for example, to solar variability and secular change in the Earth's
core-generated dynamo may be seen in geomagnetic and space physics
data records. In this session we invite contributions that illustrate
these changes and provide insights into the evolution of geospace.
Contributions that address the consequences of the evolution of
geospace are also welcomed.

IDV02 Magnetic anomalies at low lattitude (Division V and
IDCDC)
Analysis of magnetic data has been complicated by the changing
inclination of the main geomagnetic field. Interpretational tools
developed for the analysis of high latitude magnetic anomalies are
not directly applicable to low-latitudes; the analysis of low latitude
magnetic anomalies needs special attention. Papers dealing with
magnetic anomaly map generation, analysis and interpretation of
low latitude and equatorial regions are sought. Papers dealing with
magnetic anomalies derived from ground based, aeromagnetic, satellite
based or marine magnetic data are welcome.

IDV03 Swarm - Earth's magnetic field and environment explorers
The European Space Agency, ESA, has approved the mission Swarm
- Earth's Magnetic Field and Environment Explorers for full implementation
and launch in 2009 as Explorer number 5 in its Living Planet Programme.
During the 4-year operational phase the Swarm mission will complete
the International Decade of Geopotential Field Research that was
announced in a resolution adopted by IAGA and IUGG and initiated
so successfully with the launch of the Danish satellite Ørsted
in February 1999, followed by the German satellite, CHAMP and the
Argentinean satellite, SAC-C in 2000.
The objective of the Swarm mission is to provide the best ever survey
of the geomagnetic field and its temporal evolution, in order to
gain new insights into the Earth system by improving our understanding
of the Earth's interior and its electrodynamic environment. After
release from a single launcher, a side-by-side flying lower pair
of satellites at an initial altitude of 450 km and a single higher
satellite at 530 km will form the Swarm constellation. High-precision
and high-resolution measurements of the strength, direction and
variation of the magnetic field, complemented by precise navigation,
accelerometer and electric field measurements, will provide the
necessary observations that are required to separate and model various
sources of the geomagnetic field.
This short session will be dedicated to a suite of invited talks
to provide the science community with adequate information about
the mission, the science objectives, the instruments, and the expected
data products that will be made available to the users.

GAV01 Magnetic observatories: measurements, quality analysis,
and data dissemination
High-quality data from magnetic observatories and repeat stations
are crucial to the understanding of the evolution of the geomagnetic
field on a variety of time-scales from seconds to centuries. This
Symposium aims to bring together those who are involved in all aspects
of data collection as well as those researchers analyzing and interpreting
these measurements.
New contributions on magnetic observatory instrumentation, data
collection and measurement practices, as well as the scientific
evaluation of these observations will be especially welcomed.

GAV02 Indices and algorithms for detecting geomagnetic and space
weather events
Up until now SSC, SFE and bays, etc. have been catalogued by
experts either, visually analysing the records, or using semi automatic
data processing techniques. Due to current demands by users for
near real-time analysis of these data, new automatic processes and
signal analysis techniques are being developed. The aim of this
symposium is to provide the opportunity for the international research
community to review the progress and suggest future directions in
these investigations of event detection. Papers describing techniques
to detect geomagnetic events on regional or global-scale, using
ground and/or satellite data are especially welcome. Defining the
distinctive signatures of the geomagnetic events which are significant
in the solar and geophysical variability and those having applications
in space-weather predictions would be of particular interest. Papers
related to the automatic or quasi-automatic derivation and use of
geomagnetic indices are also welcome.

GAV03 High resolution marine magnetics: new techniques and experiments
All contributions addressing recent advances in marine magnetics
are welcome. Presentations of new techniques, including a variety
of newly developed instruments (sea-surface or deep-sea operated,
scalar or vector) and the methods required to interpret their data
are encouraged. Results of recent experiments designed to investigate,
among others, the magnetic structure and properties of the oceanic
crust, the magnetic signature of faults and hydrothermal activity,
the magnetization of seamounts, the time variations of the geomagnetic
field, the high resolution dating of the seafloor, would be particularly
appreciated. Marine magnetic studies about continental margins or
in shallow water environments are also very welcome.

GAV04 World Magnetic Anomaly Map: anomaly definition and calculation
The first edition of the global digital magnetic anomaly map
is aimed to represent such a component of the Earth's magnetic field
that is caused by the magnetized uppermost part of the lithosphere,
as if it were observed a few km above the Earth's surface. The anomalies
are supposed to be calculated using as similar principles as possible
everywhere. Further, the definition and anomaly calculation should
allow transforming the digital map to another reference system in
future. Well knowing the difficulties caused by temporal variation
of the recorded magnetic field and great heterogeneity in quality
and information density of available data sets the Task Force of
WDMAM of IAGA invites papers to present anomaly definitions and
practical calculation methods for major data sets. Poster presentations
are invited to display major anomaly sets reduced and compiled by
controlled methods.

GAV05 International Decade for Geopotential Research: Advances
in understanding the geomagnetic field
The 'Decade of Geopotential Research', inaugurated with the
launch of Ørsted and Sunsat in February of 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. Following 20 years
without satellite magnetic coverage, the first seven years of the
'Decade of Geopotential Research' have provided the geomagnetic
community with a wealth of high quality data from several near-Earth
satellites. Combined with ground based data, this 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.

GAV06 Uses and applications of geomagnetic field models
The aim of this symposium is to bring together users and modellers
so as to foster better interaction and mutual understanding. Have
YOU an application that modellers have not thought about? What do
users want from models of the internal and external fields and what
are the problems users have in applying models? How does truncation
level affect you? Do you have a need for a truly continuous, rather
than piece-wise continuous, internal model? Would you prefer to
use a more accurate model, even if it meant waiting to get some
model parameters (such as Dst) which are available only after considerable
delay? We need to hear from YOU about YOUR problems/preferences.
This session is for users and modelers alike, and we specifically
encourage examples of the techniques used in the application of
these models to benefit science and society. We welcome examples
by users from both the external and internal geomagnetic communities.
