A density profile vs altitude from 95 to 130 km, obtained from drag measurements are made directly from within a falling sphere, is presented. The main sensors are linear accelerometers aligned to measure X, Y, Z components of acceleration of the sphere from which total drag is obtained. The method consists of ejecting an inflatable sphere somewhere between 80 and 100 km on the ascent of an Aerobee 150 rocket flight. From ejection, the sphere continues to approximately 250 km altitude on a trajectory which is, except for drag, a free-fall trajectory. The prediction of sphere drag coefficients with their estimated probable errors are given in the altitude range from 90 to 160 km. The telemetry record showing the drag forces used in calculating the density profile in the altitude range 95 to 130 km is shown. The sources of error in the calculated density are analyzed and tabulated. The calculated density in kilograms/cu m vs altitude in kilometers is compared with the ARDC Model Atmospheres of 1956, 1959, and 1961.

The objectives of the American Meteorological Society are "the development and dissemination of knowledge of meteorology in all its phases and applications, and the advancement of its professional ideals." The organization of the Society took place in affiliation with the American Association for the Advancement of Science at Saint Louis, Missouri, December 29, 1919, and its incorporation, at Washington, D. C., January 21, 1920. The work of the Society is carried on by the Bulletin, the Journal, and Meteorological Monographs, by papers and discussions at meetings of the Society, through the offices of the Secretary and the Executive Secretary, and by correspondence. All of the Americas are represented in the membership of the Society as well as many foreign countries.

The Upper Atmosphere: Meteorology and Physics focuses on the study of the characteristics, movements, composition, and observations of the upper atmosphere. The book first offers information on the meteorological conditions in the lower stratosphere and the structure and circulation of the upper stratosphere and the mesosphere. Topics include balloon sounding systems, climatology of the lower stratosphere, disturbed circulation of the lower stratosphere, rocket measurements, and frequent measurements with balloons and meteorological rockets. The text then ponders on the sun's radiation and the upper atmosphere and composition of the stratosphere and mesosphere. The manuscript elaborates on the composition and structure of the thermosphere, including photochemical processes, diffusion, composition and structure measurements, and structure of the thermosphere. The text also ponders on radiative processes and heat transfer; atmospheric tides and winds in the lower thermosphere; and transport of properties in the upper atmosphere. The publication is a valuable source of information for readers interested in the meteorology and physics of the upper atmosphere.
