Abstract

The algorithm developed by T. Wilheim (1990) dealt with the retrieval of water vapor profiles from microwave radiometric measurements, even in the presence of clouds. This algorithm was tested with the radiometric measurements near 90 and 183 GHz frequencies, and the results are presented. It is shown that the retrieved water vapor profiles were in general agreement with those derived from the radiosonde data. In particular, the retrieval over both land and ocean surfaces generated clouds at locations that could be verified from satellite photographs. The algorithm did not perform well at places where there were surface fronts
