S10: Ionospheric storms and space weather effects

Friday, May 23, 2008 (afternoon)

Convener: R. Pfaff
Co-conveners: D. Pallamraju and L. Paxton

Description:

The association of strong plasma density variations in the mid- and low-latitude F-region ionosphere with magnetic storms continues to command much interest. This is primarily due to the fascinating and complex response of the ionosphere plasma density and dynamics to solar wind and magnetosphere influences during storm periods as well as their detrimental space weather effects with respect to radiowave communications and navigation. Experiment, theory, and modeling efforts are needed to understand the role of large-scale penetration electric fields to the low and mid-latitude ionosphere as well as other manifestations of magnetic storm effects on the global F-region ionosphere. There have been several new observations that address these phenomena, notably from the COSMIC, DEMETER, CHAMP, TIMED, ROCSAT, and DMSP satellites, GPS ground-based receivers, airglow instruments, and radars, which help provide clues to the complex plasma variations and electrodynamics of the F-region ionosphere during storms. This session welcomes presentations that address all aspects of the response of the mid- and low-latitude ionosphere to magnetic storms and their space weather effects, including in situ and ground-based observations as well as modeling and theoretical studies.
