Prediction of Equatorial Spread F Based on Assimilation of Daytime GPS Data

Abstract

Under ONR grant N00014-03-1-0243, we will explore the value of airglow imagers in the testing of assimilative models of the equatorial ionosphere. We have made data exchange agreements with both the Jet Propulsion Laboratory and the Air Force Research Laboratory in this regard. Our first goal is to verify conditions calculated by the models prior to the breakout of Equatorial Spread F (ESF), a severe ionospheric weather phenomenon. The second goal is to see if data assimilation can be used to predict these conditions and subsequently predict ESF itself. A third goal is to calibrate GPS occultation data using the Arecibo radar and then apply this method to determine the off-equatorial E-region conductivity.
