SA018:
Longitudinal Variability of Equatorial Electrodynamics, Ionospheric Irregularities, and Ambient Electron Density





Session ID#: 25400

Session Description:
Recent distributed ground and space-based observations show significant longitudinal variability of low latitude electrodynamics that directly affects the global electron density distribution and scintillation forecasting capabilities. This session attempts to address some of the longstanding questions: - what are the controlling factors that cause strong longitudinal dependence of low latitudes electrodynamics? - what is the variability of these controlling factors on different temporal scales, from daily to seasonal and intraseasonal? - how low latitude electrodynamics modifies the global electron density structures and irregularities at low and middle latitudes? We welcome papers (both modeling and observation) that describe progress in understanding equatorial electrodynamics and coupling processes that improve our ability to unravel the variability of equatorial ionosphere with longitude and to forecast global ionospheric irregularities/scintillations and ambient electron density.
