Total Electron Content Model from INTASAT Data.

摘要

Total electron content data (TEC) have been deduced, by the Faraday rotation method, from the signals of the Spanish beacon satellite INTASAT for the period Feb. 1975-Sept. 1976. The starting date of the period was established after an analysis to determine the time when the effect of the residual spinning of the satellite was negligible as compared with the Faraday effect. Monthly mean TEC values have been obtained from these data for every latitudinal degree of their subionospheric points for six half an hour intervals centered at 0900, 0930 and 1000LT in the morning and 1930, 2000 and 2030LT in the evening. These monthly values have been analyzed to obtain seasonal and latitudinal TEC variations, and a model has been deduced, that gives TEC values as a function of the latitude and the month of the year for the range of latitude of the Iberian Peninsula and the intervals stated above.
