Title: Early electrostatic probe results from Explorer 22
Abstract: The electrostatic probe experiment on Explorer 22, launched in October 1964, has permitted the concentration and temperature of the electrons at 1000 km to be observed on a global scale. The major features of the ionosphere at this altitude are a maximum concentration at the magnetic equator in the daytime and at night a pair of maximums at 35° north and south. The electron temperature exhibits large variation from day to night at latitudes below 45° but remains high all night at higher latitudes. This behavior is consistent with the heating of the protonosphere by escaping photoelectrons in the daytime, and cooling by electron thermal conduction to the lower atmosphere both day and night.
