SM32A:
Origins of Extreme Events in the Geospace I
Session ID#: 11072
Session Description:
Extreme geomagnetic and ionospheric storms are characterized by unusually enhanced amount of energy injected to the Earth ionosphere-magnetosphere system from the solar wind. This is manifested by global changes in the magnetosphere and ionosphere dynamics, as well as strong variation in Dst index. It is also known that relatively moderate storms can lead to strong disturbances in the near-Earth environment causing potential danger to human-made systems. The goal of the session is to bring together both observational and modeling studies of extreme Geospace events in order to understand their origin and inter-relations and improve predicting capabilities. We encourage contributions looking for Geospace extremes and their consequences on morphology and dynamics of ring current, radiation belts, plasmasphere, ionospheric disturbances, TEC variations etc. We invite contributions both from current Geospace missions (TWINS, Van Allen Probes, MMS, Cluster, THEMIS, GRACE) and from past missions (IMAGE, Polar, CHAMP, AMPTEE/CCE etc.)
