Recent algorithms for Special Sensor Microwave/Imager (D-MSP-SSM/I) satelli
te data are used for estimating integrated water vapour over the Indian sea
s. Integrated water vapour obtained from these algorithms is compared with
that derived from radiosonde observations at Minicoy and Port Blair islands
. Algorithm-3 of Schlussel and Emery (1990) performed best. Oil Hie basis o
f this algorithm, distribution of integrated water vapour is determined dur
ing the monsoon depression (22nd-27th July, 1992) that formed over the Bay
of Bengal.
