2020 Workshop: Ionospheric density gradients
This session provides a forum to discuss advances in understanding the fundamental storm-time dynamics in the ionosphere and thermosphere with focus on ionospheric density gradients. These remarkable ionospheric structures, of great interest to this session, include storm enhanced density, midlatitude ionospheric trough, polar tongue of ionization, polar patches, and large traveling ionospheric disturbances. We welcome contributions that characterize these storm-time features and/or address physical processes leading to their formation and evolution. Topics related to the space weather impact of these density gradients are also welcome. We expect a total of ~15 min for online presentation and follow-up discussion for each talk. The session is open to the international research community.
