Atmospheric Measurements Near 118 GHz with Passive Microwave Techniques.

Abstract

This report describes the results of ground-based passive spectral observations of the atmosphere near 60 and 118 GHz, aircraft-based 118-GHz spectral observations of the atmosphere, and theoretical evaluation of the ability of a 118-GHz passive microwave spectrometer, alone and in combination with other microwave spectrometers, to yield linear retrievals of atmospheric humidity, cloud profiles, and temperature profiles. The observed 118-GHz absorption profile was close to that expected, and the theoretical studies showed that a 118-GHz spectrometer can perform approximately as well as one at 60 GHz, although the cloud sensitivity is slightly greater.
