CEDAR email: AGU session SA004 "AIM coupling from high to low latitudes"

[XINZHAO CHU]

Dear Colleagues,

We solicit presentations for AGU session SA004 on AIM coupling from high to low latitudes.  Observations, numerical simulations, and theoretical studies are all welcome, and we hope to provide a podium to inspire science collaborations and stimulate new advances.

SA004 - Atmosphere-Ionosphere-Magnetosphere (AIM) Coupling from High to Low Latitudes

Session Description: AIM coupling takes place in broad atmospheric and geospace domains. Several recent findings regarding thermosphere-ionosphere metal (TIMt) layers provide new examples of AIM science challenges. They occur regularly in the E region (100-150 km) at midlatitudes with semidiurnal tidal phases, in stark contrast to the irregular occurrence of TIMt layers in the polar and low latitudes. Additional winter Antarctic observations reveal downwelling vertical winds below 90 km, challenging our understanding of general circulation, transport, and wave drag/sources. This session solicits observational and modeling studies aiming to understand AIM coupling from high to low latitudes. Topics include but are not limited to 1) low- and mid-latitude electrodynamics, neutral dynamics, and TIMt layers, 2) high-latitude general circulation, neutral and plasma dynamics, and persistent gravity waves, 3) responses of the stratosphere-mesosphere-thermosphere-ionosphere system to geomagnetic and solar activities, and 4) vertical and horizontal transport of global cosmic dust and minor species.

Abstract Deadline: August 4, 2021

We look forward to seeing your submission and participation in this session!
