This book was released on 1975 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: Atmospheric densities are computed from analysis of Doppler beacon satellite data. Modifications to Doppler beacon data processing program CELEST necessary for this study are described. Results obtained for satellites DB-7(6382), DB-8(6727), and DB-9(6928) are found to be in good agreement with those obtained by analysis of skin track data for the same satellites using program CADNIP.

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.

This book was released on 1966 with total page 140 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).

Available in PDF, EPUB and Kindle. Book excerpt: Experiment details and measurement technique are described for ionization gauge measurements performed onboard the Air Force S3-1 satellite. Atmospheric density data obtained over the second half of the S3-1 satellite flight are presented in the appendices in the form of graphs of atmospheric density versus altitude and universal time. These representative data were acquired during the time period from January 1975 to May 1975. A flight summary of the processed data base is provided in tabular form. See also AD-A032 373.

Available in PDF, EPUB and Kindle. Book excerpt: A triaxial piezoelectric accelerometer has been used to measure atmospheric drag acceleration on a falling sphere to determined atmospheric density. The technique allows determination of atmospheric density between 50 and 150 km, with an accuracy better than 5 percent and with an altitude resolution of about 200 m. Comparisons have been made with radar determined drag acceleration measurements, with rocketsonde measurements, and with passive Robin sphere density measurements during the same period. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: This Second Edition of An Introduction to Atmospheric Radiation has been extensively revised to address the fundamental study and quantitative measurement of the interactions of solar and terrestrial radiation with molecules, aerosols, and cloud particles in planetary atmospheres. It contains 70% new material, much of it stemming from the investigation of the atmospheric greenhouse effects of external radiative perturbations in climate systems, and the development of methodologies for inferring atmospheric and surface parameters by means of remote sensing. Liou's comprehensive treatment of the fundamentals of atmospheric radiation was developed for students, academics, and researchers in atmospheric sciences, remote sensing, and climate modeling. Balanced treatment of fundamentals and applications Includes over 170 illustrations to complement the concise description of each subject Numerous examples and hands-on exercises at the end of each chapter

Available in PDF, EPUB and Kindle. Book excerpt: An analysis of the time and space variability of density in the middle atmosphere has been developed in this report, affording a means to determine density changes that occur over distances out to 200 nmi and time periods of 1 to 72 hr. Spatial variations - The rms differences between densities at locations 50, 100, and 200 nmi apart are provided in Tables 4, 8 and 11 for low- and middle- latitude stations at altitudes from 20 through 60 km. These rms values are estimates of the day-to-day variability around the mean density gradients given in Table 5 for low latitudes and Tables 9 and 12 for middle latitudes. Time variations - The rms variability of density for time periods from 1 to 12 hr in tropical regions is given in Table 13 for altitudes up to 60 km. Estimates were derived using autocorrelation theory and an analysis of the diurnal variation of density, which is the dominant periodic cycle at low latitudes. Analyses of available density observations at several midlatitude locations for altitudes between 30 and 60 km provide reasonable estimates of the magnitude (and changes with season and latitude) of the variability of density with time for periods up to 72 hr. Variations of density at these latitudes are relatively small during summer and do not increase significantly with time. Rms variations remain between 1-1/2 and 4 percent for all periods up to 72 hr.
