Atmospheric Structure and Its Variations in the Region from 25 to 120 km
Abstract
The report has been prepared as part of the activities of the Committee on Space Research (COSPAR) panel on a new reference atmosphere, which will aid in the design of aircraft, missiles and satellites. It combines a review of observational results obtained over approximately the last six years on temperature, pressure, density and winds with new models for the seasonal and latitudinal dependence of these parameters at heights from 25 km to the lower thermosphere. The temperature, pressure and density models extend from 25 to 110 km and are identical with those previously given in Report AFCRL-70-0261, May 1970 (Air Force Surveys in Geophysics, No. 218). W-E wind models are presented separately for the regions 25 to 60 km and 60 to (approximately) 120 km. Three W-E wind models from 25 to 60 km are presented corresponding to N. American data, European/W. Asian data, and S. Hemisphere data. A model for the quasi-biennial oscillation in W-E winds at low latitudes is given. Other variations, such as diurnal (tidal) variations, and S-N winds are dealt with in the review of observational data.
