Abstract: Employing 211 nocturnal radiometersonde observations of upward upward infrared flux, air temperature, and relative humidity in the atmosphere, the water vapor flux emissivity as a function of optical depth has been determined. ...

Abstract: Further data are presented to indicate the accuracy of the airborne economical radiometer (frequently termed radiometersonde when used in a modified radiosonde system) in the measurement of infrared radiation, in view of ...

Abstract: A graphical technique for estimating areal precipitation patterns associated with given contemporary charts of streamlines and isotachs and of moisture at four selected levels is developed from the basic physical considerations ...

Abstract: Measurements of the effective long-wave emissivity of clouds, equivalent to one minus the slab transmissivity, are obtained through thermal energy relations at cloud tops and bases after the manner of Gergen. Radiometric ...

Abstract: The local ozone concentration and water vapor overburden were measured from a WB-57F aircraft near thunderstorms that reached or penetrated the tropopause. Two storms were studied extensively: one that penetrated 800 m ...

Abstract: Thin layers of particulates or clouds in the high troposphere and lower stratosphere are generally not visible to an observer at the surface, even under the favorable viewing conditions at sunset. They are not easily ...

Abstract: A radiometric method for the retrieval of moisture data at altitudes above the radiosonde hygristor cutoff region or in situations where a malfunction of the hygristor occurs is described. The method was applied to BOMEX ...

Abstract: By varying the amount of water vapor as input to the radiative power transfer equation, assuming a constant carbon dioxide and varying ozone distribution, it is possible to infer stratospheric water vapor from broadband ...

Abstract: Based on aircraft measurements of the radiant emittance of cirrus clouds and cloudless sky, the 8-13? infrared transmissivity of high cirrus clouds was calculated. The measurements and applied calculations were made for ...
