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

Abstract

GPS systems have become very important for space weather prediction, since many observations can be assimilated worldwide. Before doing so, it is important to verify the reliability of the measurements and their limitations. Under this grant, we used the Arecibo radar to carry out such collaborations. Using the available analysis methods, we found that E-region observations with GPS were very unreliable. The F-region profiles were much better but we did find systematic differences, particularly in the height of the maximum in electron density. These results have led to improved algorithms for profile generation using GPS.
