Preliminary Results on TID (Travelling Ionospheric Disturbances) over Ebro from TEC Data.

Abstract

Faraday rotation data recorded at the Ebro Observatory in January 1979 have been analyzed by the maximum entropy method to obtain the spectrum of TID's travelling through the station. The results indicate that most of the TID's in this month have periods shorter than 30 minutes and appear only between 7hr and 20hr UT. Their diurnal variation depends on their frequency. A less sophisticated analysis of the data of the whole year shows a clear seasonal dependence of the number, period and diurnal variation of TID's. (Author)
