G07: Radio Studies of Equatorial and Low-Latitude Aeronomy

Wednesday, August 20  13:40-15:20,  Room #14

This session covers the wide-range of equatorial phenomena observed by radar and radio instrumentation. Papers are solicited on topics that include instability processes and irregularities associated with the equatorial electrojet and the equatorial ionization anomaly. In addition, papers are solicited on topics that cover the coupling between the different atmospheric regions (Mesosphere and Lower Thermosphere and Magnetosphere/Ionosphere coupling) and different atmospheric drivers (ionospheric dynamics and electrodynamics) in the equatorial region.  New trends, techniques and experiments, important scientific issues and future directions of equatorial and low-latitude aeronomy will be covered.
