ISEA 12 Poster Session P4 for sessions S9 and S10

Friday, May 23, 2008 (evening)

Conveners: D. Hysell (S9) and R. Pfaff (S10)
Poster chairs: M. Nicolls and E. de Paula

S9: New techniques, experiments, campaigns, and results

Description:

We invite talks pertaining to experimental results and findings from recent campaigns, new instruments and facilities, and emerging techniques in equatorial aeronomy. A number of rocket and multi-radar experiments have been performed since the last ISEA, and results are solicited, particularly those combining ground- and space-based observations and addressing coupled E and F region processes. Likewise, a number of new satellites have or will have been launched in time for the meeting, and first results may be presented in this session. Updates on new experiments and capabilities at Jicamarca, the EAR, Arecibo, and other low- and middle-latitude radar facilities are also solicited, as are reports on low- and middle-latitude HF radars. Reports from new and planned airglow instruments and lidars are also being sought. Emerging techniques of interest include radar interferometry and imaging, incoherent scatter analysis, satellite occultation measurements, ionospheric tomography, daytime optical aeronomy, space-based imaging, in situ measurements, and experiments involving chains and clusters of instruments.

 

S10: Ionospheric storms and space weather effects

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.
