SA23D:
Neutral Winds, Currents, and Electric Fields at Low- and Midlatitudes below 200 km: A Critical Review of Our Knowledge and Understanding II Posters


Session ID#: 8886

Session Description:
Ever since the earliest measurements of the low/mid-latitude ionosphere, researchers have sought to understand the motions of the upper atmosphere and how they influence the generation of electric fields and currents.  This session invites a fresh look at this basic ion-neutral coupling below 200 km.  One focus is the daytime dynamo and its related electrodynamics.  Whereas it is generally accepted that tides account for the forcing through which Sq currents are set up, new rocket measurements in the daytime ionosphere of simultaneous winds, currents, and electric fields shed new light on this global phenomenon and its variability.  Further, advances in modeling, increased ground magnetometers, and expected observations from NASA’s ICON mission, suggest future research will advance our understanding of the low/mid-latitude electrodynamics by a large degree.  This session sets the stage for a critical evaluation of what we know and don’t know about low/mid-latitude winds and associated electrodynamics.
