Measurements of electron concentration in the ionosphere up to altitudes of 420–470 km, carried out during the international geophysical year by means of radio-wave transmissions from the geophysical rockets of the academy of sciences U.S.S.R.

Abstract

Problems relating to methods for measuring radio-wave dispersion and the Faraday effect, as employed in the determination of the electron concentration, are examined. Results of measurements carried out during the launching of 3 geophysical rockets to 450 to 470 km altitude, in l958, are presented. Measurements were performed at different times of the day and year, over the same geographicaI point, and by the same method. The n/sub e/ distribution with altitude was determined for the outer ionosphere. (L.N.N.)
