Book Synopsis Atmospheric Density Variations in the Southern Hemisphere at Low Satellite Altitudes by : F. A. Marcos
Download or read book Atmospheric Density Variations in the Southern Hemisphere at Low Satellite Altitudes written by F. A. Marcos and published by . This book was released on 1975 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Accurate density measurements are required to develop predictive atmospheric models. Of particular concern is the altitude region below 250 km. Few measurements are presently available in this region and data are urgently required by the Air Force for accurate ephemeris, trajectory, and reentry predictions. Profiles of neutral atmospheric density obtained at low satellite altitudes in the southern hemisphere during geomagnetically quiet conditions are described in this report.
Book Synopsis Lower-thermosphere Neutral Density Profiles Derived from Satellite Accelerometer Data by : F. A. Marcos
Download or read book Lower-thermosphere Neutral Density Profiles Derived from Satellite Accelerometer Data written by F. A. Marcos and published by . This book was released on 1976 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Cannon Ball II and SPADES satellites carried triaxial accelerometer systems for accurate measurement of neutral atmospheric density. Cannon Ball II was launched 6 August 1971 into a polar elliptic orbit in which the initial perigee was at the extremely low altitude of 132 km. SPADES was launched 11 July 1968 into a polar elliptic orbit in which the initial perigee was at 155 km. The data, analyzed to deduce an average density profile for each satellite for summer conditions in the northern hemisphere, are for the altitude region 135 to 250 km, where measurements have heretofore been extremely sparse. Comparisons were made with recent models and experimental data. These results are intended to be supplemented by those of lower-thermosphere studies now being carried out on accelerometer data from the Atmosphere Explorer satellites and a low-altitude Air Force satellite. Comprehensive analyses of accelerometer data low-altitude satellites will allow accurate modeling of the lower thermosphere. These models are required for improving calculation of the trajectories of Air Force systems vehicles and other spacecraft.

Book Synopsis Atlas of Northern Hemisphere Density Between 30 and 60 Km by : Arthur J. Kantor
Download or read book Atlas of Northern Hemisphere Density Between 30 and 60 Km written by Arthur J. Kantor and published by . This book was released on 1982 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mean seasonal density charts for the Northern hemisphere for 5-km increments of altitude between 30 and 60 km are presented in this report, along with estimates of the day-to-day variations around the mean seasonal values. This meets the need for a climatology of atmospheric density at constant altitudes above radiosonde levels. These charts are based on compilations of data by workers at the National Meteorological Center, NOAA, who combined data from TIROS operational vertical sounders with meteorological rocketsonde observations to produce once-weekly analyses of height and temperature fields for the Northern hemisphere at the 5, 2, 1, and .4 mb levels for the period July 1976 through April 1980.

This book was released on 1966 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: A knowledge of atmospheric density and its variation at satellite altitudes is needed for operational support of several military activities. Atmospheric density data computed from the decay rates of more than 40 satellites orbited during a five-year period were analyzed during this investigation. Multiple regression equations were derived to specify the density at 10-km intervals at altitudes from 180 to 300 km as a function of solar activity, time of day, time of year, and combinations of these variables. Density values depicted by these regression equations were then compared with density data which had not been used during the derivation of the equations. The results of this investigation indicate that multiple regression analysis and the associated screening procedure can produce equations from which computed density values are in close agreement with observed density data. The results lead to a conclusion that no single density model can meet all needs. These results also indicate that characteristics of a density model should be selected to fit the purpose for which the model is intended. Four possible density models designed for different purposes are suggested. (Author).
