DENSITY OF THE ATMOSPHERE ABOVE 120 KILOMETERS AS DERIVED FROM SATELLITE MEASUREMENTS.

Abstract

Satellite measurements have indicated that there are large time variations in density at heights above 200 km. These variations have been correlated with the level of activity of the sun, magnetic storms, and position on the earth relative to the sub-solar point. This paper is a survey of the use of satellite drag perturbations to measure atmospheric density. It includes a discussion of three of the most important atmospheric models that have resulted from satellite measurements, concluding with the Static Diffusion Models by Luigi G. Jacchia of the Smithsonian Institute. An extensive bibliography is included. (Author)
