3. Call for Papers for 2003 Joint URSI/IEEE Meeting Session on
“Remote Sensing from Space”
————————————————————–
From: Gordon James and
Bodo Reinisch

We draw your attention to the “Remote Sensing from Space” session at the
upcoming 2003 URSI North American Radio Science Meeting and IEEE
International Symposium on Antennas and Propagation, to be held in Columbus,
Ohio, 22-27 June 2003 (http://aps2003.eng.ohio-state.edu/). We invite the
submission of one-page abstracts by you and your colleagues. The abstracts
are due 8 January 2003 (hard copy) or 15 January 2003 for Web submissions.
This session is organized jointly by Commissions G and H.

A short description of our session is below. We encourage you to submit your
abstracts on-line, with email copies to the co-convenors listed at the bottom.

There will be an URSI Student Paper Contest sponsored by USNC and CNC. The
student paper submission due date is 3 January 2003. Four prizes ($125, 250,
500 and 1000) will be awarded in addition to payment of travel and
subsistence expenses of the four finalists. Notice that a submission to the
Student Competition DOES NOT constitute a submission for the regular program.
If a student wishes a paper to be included in the regular program, the
submission procedure and format outlined for abstract submission must be
followed in addition to the paper submission. See the web site for more
information.

“Remote Sensing from Space”:
A variety of radio techniques are available for remote sensing of the
Earth’s plasma environment from spacecraft. The oldest method, yet still
heavily used, has been the passive observation of spontaneous processes
creating waves at frequencies characteristic of plasma parameters at their
source. Techniques such as direction-of-arrival determination and spectral
analysis of components of wave electric and magnetic fields have been
developed and improved. Likewise, radio sounders continue to develop and
supply new perceptions of the ionosphere-magnetosphere system. The refraction
and scattering of transmitted electromagnetic waves are phenomena currently
exploited to trace the topology of structures. The advent of multi-spacecraft
observations signals new capability in resolving plasma processes occurring
at a distance.
We call for observational results from active or passive wave instruments
working in the solar-terrestrial system. All aspects of the metrology of
remote radio sensing of space plasmas are invited. Submissions about the
analysis of data for determining the topologies of distant space plasmas are
requested. Treatments of multiwave component data for the extraction of wave
distribution functions are appropriate for this session. We welcome papers
using any of these concepts as the basis of interpretation of the structure
or dynamics of the ionosphere-magnetosphere.

“Ionospheric Imaging”:
With the recent advances in new remote sensing instrumentation, new
satellite missions, and advanced computer techniques, we have now a
capability to image the ionosphere with unprecedented resolution and
accuracy. As such, it is a good time for all scientists interested in
ionospheric imaging to come together and exchange ideas on imaging
sensors, retrieval and inversion algorithms, and areas of basic
science and space weather applications that ionospheric imaging can be
applied to.
Therefore, this session will focus on imaging the ionosphere using
remote sensing methods. For our purposes, ionospheric imaging refers
to any instrument and retrieval method that produces 1D-3D images of
fundamental ionospheric variables such as electron density. Imaging
methods include RF tomography methods, GPS TEC map methods, imaging
from FUV and EUV sensors, profiles extracted from GPS occultation
sensors and other methods.
Topics suitable for this session include new instruments and methods,
inversion techniques and algorithms, and scientific as well as
space weather applications of ionospheric imaging.

5. First Announcement of IAU Joint Discussion on “Magnetic Fields and
Helicity in the Sun and Heliosphere”
———————————————————————
From: David Rust

INTERNATIONAL ASTRONOMICAL UNION
JOINT DISCUSSION ON MAGNETIC FIELDS AND
HELICITY IN THE SUN AND HELIOSPHERE

RATIONALE
In the past decade, the Yohkoh, SoHO, and TRACE space missions have
provided millions of pictures of flare activity, coronal mass ejections
(CMEs), filament eruptions, and other dramatic solar events. What is the
physics behind the pictures? We are sure that the main agent responsible
is the solar magnetic field. Emergence of magnetic flux leads to
instabilities in the atmosphere, magnetic reconnection, and eruptions.
But recently it was demonstrated that the magnetic field was not the
only important index of potential activity. The magnetic helicity of the
system appears to be a crucial parameter.
IAU Joint Discussion 03 will focus on how magnetic helicity is spawned
and shed by the sun. As magnetic helicity from the internal dynamo or
elsewhere accumulates at the solar surface, twisted flux ropes rise into
the corona, apparently carrying helicity with them. Sometimes a CME
follows. The CMEs ejected during the solar cycle may relieve the sun of
its dynamo-generated flux and helicity. What are the details of this
picture? Is it correct in general outline? These points will be
discussed from an observational point of view as well as a theoretical one.

PRELIMINARY PROGRAM (with invited speakers)

1. Magnetic helicity generation inside the sun (P. GILMAN)
2. Solar dynamos under the constraint of magnetic helicity conservation
(A. BRANDENBURG)
3. Limits of magnetic helicity conservation in solar and heliospheric
plasmas (M. BERGER)
4. Sources and sinks for helicity in the corona (K. KUSANO)
5. Techniques for inferring active region magnetic helicity content
(J. CHAE)
6. Magnetic helicity generation and signature in the solar atmosphere
(A. PEVTSOV)
7. Magnetic helicity in filaments, coronal mass ejections and magnetic
clouds (D. RUST)
8. Spectrum of magnetic helicity in the solar wind (W. MATTHAEUS, not yet
confirmed)
9. Role of magnetic helicity in solar flares (TBD)

The Joint Discussion will take place during the IAU General Assembly in
Sydney, Australia, July 13-26, 2003. It is organized by IAU Division
II – Participating Commissions: 10, 12 & 49
Scientific Organizing Committee: M. Berger (UK), D. Canfield (USA), J.
Chae (Korea), G. Field (USA), C. Mandrini (Argentina), D. Melrose
(Australia), D. Rust (USA, Co-Chair), B. Schmieder (France, Co-Chair),
K. Shibata (Japan) & V. Yurchyshyn (Ukraine).
