Ionospheric Electron Production Rate for Grazing Incidence at the Ebro Observatory by Luis F Alberca Silva( Book )

3 editions published between 1977 and 1979 in English and held by 3 WorldCat member libraries worldwide

Values of total electron content of the ionosphere, obtained at the Observatorio del Ebro by the Faraday rotation method, have been analyzed to study electron production rates. Daily values of the electron production rate, integrated with respect to height through the ionosphere, were determined at sunrise for the period August 1973-Jul 1974, by a method that makes use of a two components model atmosphere. A Fourier analysis of the results indicates an annual and a semiannual variation of the production rate values. A comparison with results of other authors seems to indicate a latitudinal dependence of the semiannual variation; no similar effects was found for the annual variation. (Author)

Total Electron Content Lunar Variation at Two Midlatitude Stations( Book )

1 edition published in 1980 in English and held by 1 WorldCat member library worldwide

Total electron content data of a year of the Ebro and Hamilton stations have been analyzed by the Chapman-Miller method and the components of the solar and lunar tides at both stations obtained. The same analysis has been performed with the data grouped by seasons. All results but the ones corresponding to Ebro equinoxes, are significant at the 5% level, and agree with results of other authors. The non-significance of the equinoxes results seems to be related to the location of the focus of the dynamo ionospheric currents. Also the semimonthly lunar tide and its diurnal solar variation are obtained and the results are discussed. (Author)
Total Electron Content Model from Intasat Data( Book )

1 edition published in 1979 in English and held by 1 WorldCat member library worldwide

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.

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

1 edition published in 1982 in English and held by 1 WorldCat member library worldwide

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)
Lunar Variation of Several Ionospheric Parameters( Book )

1 edition published in 1981 in English and held by 1 WorldCat member library worldwide

The first four harmonics of the diurnal lunar variation and the semimonthly lunar tide of two years TEC data at Ebro and at Hamilton, and for some other ionospheric parameters at Ebro have been obtained. For the parameters with sufficient number of data, the lunar harmonics for the different seasons have also been obtained. The relation between the diurnal lunar variation of the height and the electron density of the maximum of the F2 layer seems to be solar dependent with a change of the phase at about 1000 SLT. The diurnal solar variation of the semimonthly lunar tide is also discussed. (Author)
