Abstract : Radar data from Jicamarca, Peru and phase fluctuation data from Arequipa, Santiago and Kourou were used to study the occurrence and intensity of phase fluctuations of GPS signals. In the study of 14 days of campaign equatorial data, there was a longitudinal separation of 5.5 degrees between the overhead field line at the radar site at Jicamarca and the overhead field line at Arequipa. At times thin layers were shown on the radar but plumes appeared to develop to the east showing a lack of correlation even over small distances. We have started a study to relate GPS phase fluctuations at the equator with the Bz component of a high latitude magnetogram; for this initial study there was a lack of correlation between magnetic activity and phase fluctuation but more complex studies involving a larger data base and more attention to ambient conditions will be instituted in the future.
