Abstract: Knowledge of the air density at altitudes above 30 km is needed for such applications as the calculation of space shuttle reentry heating. A method is described for deriving hemispheric (or global) horizontal density fields ...

Abstract: Satellite-measured radiances offer the first opportunity for investigating the total structure of winter stratospheric warmings, a phenomenon whose cause is still unknown despite intensive study since 1952, Vertical ...

Abstract: A review of engineering and research data requirements for altitudes 30?100 km is made, indicating a variety of concrete data applications above 30 km (10 mb). The required data have in large measure been provided from ...

Abstract: The compatibility of rocket observational results in the Arctic and Antarctic is examined for altitudes in the upper stratosphere. Atmospheric densities are derived from rocket pressure gage and thermistor observations at ...

Abstract: Knowledge of the horizontal variation of density is required in a number of problems, such as the calculation of aerodynamic heating rates of lifting reentry vehicles in near-horizontal flight. On constant-pressure surfaces ...

Abstract: Radiance measurements made by the Satellite Infrared Spectrometers (SIRS A and B) and Vertical Temperature Profile Radiometers (VTPR) in 1969?74 comprise a basically uniform observational data source, in view of the ...

Abstract: Relationships among the high-latitude stratospheric zonal wind, the tropospheric zonal wind in the region of the subtropical jet and over the equator, the Southern Oscillation, and the stratospheric tropical quasi-biennial ...
