Available in PDF, EPUB and Kindle. Book excerpt: 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).

Book excerpt: This report provides descriptions of environmental models used in the near-earth environment for the analysis of earth-based and satellite data. Included are models of the ionosphere, atmosphere, radiation belt, Earth's magnetic field, and orbital prediction. These models are used at PL for a variety of purposes, in particular, for the analysis of experimental data obtained from ground based instruments and, where applicable, instruments carried on balloons, rockets, and satellites. Some of the models described here were developed at PL based upon such measurements. For many of the models described here, computer output is provided together with estimates of computer (CPU) times required to generate such output. The computer codes (subroutines) for these models are frequently incorporated into programs used for data analysis and reduction, as well as mission planning. It is hoped that this report will serve as a useful reference for planning such future missions.

This book was released on 1967 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: Analysis of neutral density data has made it possible to extend curves of mean density as a function of latitude and season from 90 to 120 km. There is an approximate isopycnic point at 91 km. Above this point the density variations are reversed from what they are at 80 km. In other words, at 120 km the density in summer and at the tropics is lower than that in CIRA 1965 and in winter the density is higher. The density curves have been idealized near 120 km to join at one of three points. These correspond to typical summer and tropical conditions, winter conditions, and spring/autumn conditions. The summer density is 20 percent below that of the U.S. Standard, the winter density is 50 percent above the Standard and the spring/autumn density is 1 percent above the Standard. By application of appropriate theory the corresponding variations in temperature and mean molecular weight have been calculated. An unexpected result of the theory is the prediction of a seasonal variation of the mean molecular weight. Some of the data presented in the paper have been analyzed since the models were derived. These data have been found to be acceptably close to the models. (Author).
