*************************** ** THE GEM MESSENGER ** *************************** Volume 17, Number 3 January 31, 2007 ---------------------------------------------------------------------------- Call for GEM Participation in Joint Assembly Special Session: "Observational Constraints on Radiation Belt Dynamics" ---------------------------------------------------------------------------- From: Geoff Reeves and Paul O'Brien Dear GEM community We would like to draw your attention to a special session at the 2007 Joint Assembly in Acapulco Mexico. This session (as well as SM03 and SM07) were initiated following discussions at last year's GEM IM/S sessions when participants agreed that there was a need for more discussion-oriented sessions at AGU meetings. This spring's Joint Assembly seemed like the perfect place to kick off that experiment. SM04 is titled "Observational Constraints on Radiation Belt Dynamics". The session description is below. The session will include several short, informal talks that lay the groundwork for more general discussion by participants. Please consider joining us in this experiment. Suggestions and comments are welcome. Thanks, Geoff Reeves & Paul O'Brien 2007 Joint Assembly, Acapulco SM04: Observational constraints on radiation belt dynamics Session Description: The dynamics of the Earth's radiation belt continue to present challenges to the science community that studies them. The outer zone radiation belt dynamics problem has been divided roughly into the study of acceleration and loss mechanisms, each of which consists of a relatively small number of candidate mechanisms. With observations from scientific and operational vehicles, there are many opportunities to constrain theories of electron dynamics. The inner zone and slot regions are comparatively harder to examine observationally, because of the relative scarcity of observations. Nonetheless, recent progress has been made toward a description of the short-term and long-term dynamics of these regions. We call for contributions on recent advances in radiation belt science, with special emphasis on the connection between observations and theoretical and numerical tools that are needed to lay the foundations for missions such as the Radiation Belt Storm Probes (RBSP) – namely to understand and enable prediction of radiation belt dynamics and the risks to satellites and space exploration. Any oral sessions assigned to this special session will be intentionally informal, with short presentations followed by open discussion time.
