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.
