Microwave Radiometric Detection of Atmospheric Internal Waves

Abstract

Microwave radiometers have, for the first time, detected internal waves in the atmospheric boundary layer and localized their altitude. Varying the intersection height of a narrow (3 deg) antenna beam with that of a wide (22 deg) vertically pointing antenna beam allowed determination of the wave altitudes. The ground-based radiometers were located at San Diego, where, in an experiment in may- June 1975, the Naval Electronics Laboratory Center (NELC) provided 'atmospheric-truth' for comparison to the radiometer data obtained by the Naval Research Laboratory. NELC provided FM-CW radar, acoustic sounder, lidar, microbarograph, radiosonde, and surface meteorological data. Preliminary results showed cases of correspondence between the signals of the passive radiometers and the active FM-CW radar and acoustic sounder systems. Examples included internal wave trains up to an hour in length.
