Measurements of electron concentration and electron temperatures by the Langmuir probe experiment of the Explorer 22 satellite during 1966 are employed to study the response of the topside ionosphere, at 1000 km, to magnetic storms. The analysis was limited to the American longitudes (50° to 130°W) over a latitude range from 50°S to 70°N geomagnetic. The daytime response is characterized by various degrees of electron-density enhancements over the entire latitude range, with the winter high latitudes undergoing highest enhancement. The electron-temperature changes are not so unique. An attempt is made to explain some of these features qualitatively, based on thermal expansion of the upper atmosphere during storms and the ‘viscous drag’ of the solar plasma on the magnetosphere.
