Abstract:

Theory and numerical analysis of data were applied to a number of leading problems of atmospheric structure in the upper mesospherelower thermosphere during the three years of theis project. Three investigations occupied the first 18 months and concerned 1 Diurnal and semidiurnal tidal dissipation of momentum and energy in the upper atmosphere, 2 The modelling of O distribution from 85 km to the turbopause and 3 An empirical model for solar cycle changes in mesospheric structure. During the second part of the project, attention was concentrated on 4 Atmospheric modelling of the intermediate region 70-130km between given models for the lower up to 70 km region and the upper above 130 km region. A preliminary report of this work, to the extent that it might meet the needs of a new COSPAR reference atmosphere, was presented at the 1986 COSPAR meeting and a detailed report of the theory and analyses was subsequently completed.
