The Indian Satellite Bhaskara has onboard a microwave radiometer (SAMIR) with two channels; one in. 19:35 GHz and the other in 22.235 GHz. Data from the radiometer has been used for the determination of Integrated water vapour and liquid water content over oceans. The regularisation method of regression analysis suggested by Grody (1976) which follows directly from radiative transfer theory has been used. The satellite derived water vapour content has been compared with nearest radiosonde observations and APT pictures. The Bhaskara passes for orbit Nos. 300, 314, 329 dated June 27, 28 and 29 were analysed and the results are discussed.
