Abstract:

Total Electron Content TEC was determined between October, 1975 and August, 1976 from measurements of the Faraday rotation of a plane polarized wave transmitted at 140 MHz from the geostationary satellite ATS 6, located at approximately 35 deg E over the equator. The computed results are presented as diurnal variations for single days and monthly means. Maximum daytime TEC values were observed in April about 20 x 10 to the 16th power elsq. m and minimum in January about 9 x 10 to the 16th power elsq. m maximum night-time values were observed in January and February about 3 x 10 to the 16th power elsq. m. The response of TEC to the high magnetic activity associated with substorms was found to depend greatly on the time of day when the storm occurred. Author
