TABLES OF NEUTRAL ATMOSPHERIC PROPERTIES AS A FUNCTION OF SOLAR ACTIVITY AND LOCAL TIME FROM 90 TO 10,000 KM,
Abstract
A semi-theoretical model of the upper atmosphere has been constructed to allow the calculation of the primary neutral atmospheric properties (temperature, density, pressure, and composition) from 90 to 10,000 km as a function of local time and solar activity. The results of these calculations are presented in the form of tables for various local times and solar activities ranging over a solar cycle. The density in the exosphere is corrected for the escape of atomic hydrogen from the Earth's atmosphere. In order to check the model, the temperature, molecular weight, density and number densities for O, O2, and N2 are computed from 130 to 200 km for conditions of solar activity and local time corresponding to measurements made by Nier et al. (Neutral composition of the atmosphere in the 100- to 200-kilometer range, J. Geophys. Res., 69:979-989 (1964)) at White Sands on June 6, 1963. The observed properties and those calculated with the model differ by an average of 10 per cent. (Author)
