A formulation is presented for modeling neutral atmosphere structure in an intermediate height region (70-130 km) between given lower and upper models in temperature, pressure, density and constituent gas concentrations and to maintain continuity in the second derivative of temperature and the other properties with respect to height. The method employs temperature as the prime parameter requiring simultaneously a best fit to available temperature data at the intermediate heights and hydrostatic consistency between the nitrogen partial pressures at 70 and 130 km. The method is well suited to upper and lower models that have analytical representations and is developed as the upper model and for polynomially-generated height-latitude cross-sections in the lower region. Attention is given to comparisons between observed and model temperatures and it is found that mid-latitude data (primarily obtained using the incoherent scatter technique) are on average higher than the models due to the requirement to maintain hydrostatic consistency in nitrogen partial pressures between the 70 km and 130 km values of the given lower and upper models. This discrepancy which at present remains an unresolved problem is discussed in the text. Tables of temperature, pressure, and density are included in the report based on the best fit to available data and simultaneously satisfying the constraints of the upper and lower models. Keywords: Temperature; Mesosphere; Pressure; Lower thermosphere; Density; Model atmospheres. (JHD).

Theory and numerical analysis of data were applied to a number of leading problems of atmospheric structure in the upper mesosphere/lower 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.
