Density Variations in the Heterosphere
Abstract
Five separate types of density variations are recognized in the upper atmosphere at satellite heights. These are: (1) day-to-night variations, (2) variations with solar activity, (3) variations with geomagnetic activity, (4) semiannual variations, and (5) latitude-dependent seasonal variations. Each type of variation is reviewed, together with the present state of knowledge concerning its origin.
