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: This paper develops an objective technique for estimating the mass and energy exchange in convection systems corresponding to altocumulus cumulogenitus and cumulonimbus intensities using measurements of the area change of ...

Abstract: A conventional Eppley Pyrheliometer was converted into a beam reflector by mounting it, upright, in the prime focus of a parabolic mirror. This unit, attached to an aircraft, provides a means of obtaining reflected short-wave ...

Abstract: In this paper we have used time-lapse ATS-I satellite cloud photographs as our data source for the evaluation of the convective transport of latent heat from the lower troposphere to the tropical upper troposphere. The ...

Abstract: An improved net-radiation instrument for measuring the net flux of radiant energy through a surface parallel to the earth's surface, which employs the principle of exposing a ventilated radiation-absorbing element to the ...

Abstract: Results and conclusions drawn from 50 radiometer-sonde ascents over Wisconsin are presented. Atmospheric infrared radiation flux is separated into upward, downward, and net components. Radiation divergence and resulting ...

Abstract: Nimbus 4 data (11.5-?m) channel and ATS 3 digitized data were analyzed for three days during April and May, 1970. Cloud-top temperature, as measured by the 11.5-?m channel of the satellite radiometer, shows a close negative ...

Abstract: Time series of areal cloud coverage over the central Pacific are studied to determine the large-scale variations of tropical disturbance activity for a four-month period in 1967. The persistent and fluctuating components ...
