Description: A radical new set of model atmospheres was prepared which represent typical atmospheric conditions for summer and winter at various latitudes up to 60 deg and which above 120 km are also functions of time of day and solar flux. These atmospheres connect at 80 km with Cole and Kantor's winter atmospheres for 30, 45, and 60 deg latitude, with their tropical atmosphere for 15 deg latitude and with their summer atmospheres for 30, 45, and 60 deg latitude. The three winter atmospheres merge at a common point at 120 km, with a density 50 percent above U.S. Standard 1962. The three summer atmospheres, plus the tropical atmosphere, merge at 120 km, with a density 20 percent below the U.S. Standard. In addition, a mean atmosphere has been prepared between 80 and 120 km which, in effect, constitutes a revision of the Standard. This atmosphere represents an average over all conditions, but also can be used for spring and fall at latitudes of 30 deg and higher. Each atmosphere has been calculated with a value of the acceleration due to gravity appropriate to the latitude. Starting from the three common points at 120 km are three sets of atmospheres. Each set consists of a number of atmospheres corresponding to exospheric temperatures lying between 600 and 2100K. At the higher altitudes, the seasonal dependence disappears and the variation is diurnal and with solar flux. These atmospheres are calculated using the acceleration due to gravity for a latitude of 45 deg. (Author).
