Global Frequency Distribution of Exospheric Temperature
Abstract
The distribution of exospheric temperature under all conditions of solar and geomagnetic activity and of spatial location was determined for two different models of the earth's thermosphere and exosphere. The two models were the 1971 Jacchia model and the U.S. Standard Atmosphere Supplements, 1966. Data from the past 12 solar cycles were used to determine the contribution of solar activity to the distributions. The contribution of geomagnetic activity was based on the distribution of geomagnetic activity for solar cycle 20. The spatial contribution was determined by analysis of the diurnal variation in exospheric temperature as given by the particular model. The resulting distributions indicate a mean exospheric temperature of approximately 900 K for either model.
