Dear colleagues,

We would like to invite you to submit an abstract to the upcoming IUGG
meeting, which will be held in Melbourne, Australia in 2011. The session
we are running is entitled "A07.1 Radiation Belt Dynamics: drivers and
impacts of acceleration and loss processes", and will focus on various
aspects of radiation belt dynamics (please see abstract below).

Our session is part of the IAGA meeting within IUGG, and will be held
during the week 2-7 July 2011 (IUGG itself runs from 28 June - 7 July
2011).  Abstract submission is now open and the deadline is Monday 17
January 2011. Early bird registration is open until 11 April 2011.

More information on the IUGG conference, the schedule, and the city of
Melbourne can be found on the conference website at
http://www.iugg2011.com/  We look forward to seeing you there.

A07.1 Radiation Belt Dynamics: drivers and impacts of acceleration and
loss processes
Organiser: IAGA Div II and Div III
Lead Convenor: Mark Clilverd (United Kingdom)
Co-Convenors: Craig Rodger (New Zealand), Jacob Bortnik (United States of

Scope: 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. Particle
precipitation into the atmosphere is one of the mechanisms for energetic
electron loss from the Van Allen radiation belts, and has consequences for
the lower atmosphere. This is particularly significant during and after
geomagnetic storms, when the radiation-belt loss rate, and the source
population, can both increase.  In this session, we will focus on the
dynamical behaviour of radiation-belt and ring-current particles, the
global variability and coupling to the inner magnetosphere, the nature and
spatiotemporal distribution energetic particle precipitation into the
D-region, and the consequences for the underlying atmosphere. In
particular we seek contributions demonstrating the spatiotemporal
distribution of various waves (including electromagnetic ion cyclotron
(EMIC), chorus wave activity, magnetosonic, ECH and other); the role of
the ring current in global magnetopause losses; the role of ultra low
frequency (ULF) waves in energizing radiation belt particles; and the
precipitation of energetic electrons (>20 keV) into the D-region
ionosphere and below - through ground-based and satellite experimental
observations, as well as theoretical investigations.
