Session Proposal: Exploring E-Region Dynamics: From Theory to Forecasting, Observations and Emerging Applications (AGU25)

SA012
Exploring E-Region Dynamics: From Theory to Forecasting, Observations and Emerging Applications

Session ID#: 252241

Session Description:
During the last century, there have been significant advances in understanding E-region physics, and the E-layer has been routinely used by high-frequency (HF) radio and ground radar operators. This session welcomes abstracts that highlight the latest advancements in understanding of the E-region dynamics, as well as open questions related to sporadic E-layer forecast, lower E-layer formation mechanism, as well as novel applications. Papers related to theory, observations, experiments, modeling, E-region data assimilation and neutral density forecasting, and other applications are all encouraged. The session also aims to hear about observations of neutral winds and neutral densities that could further help to investigate various E-region phenomena.
