Abstract: Measurements of sea surface temperature (SST) were made in the Arabian Sea and the Bay of Bengal using an air-borne infrared radiometer (10.4-12.2 µm) during monsoon of 1977. Eight successful aircraft flights were made from levels lying between 600 and 1800 m. The temperature corrections which were applied to retrieve the SST from the observed IR radiances were estimated from a temperature correction scheme [Sinha H S S et al., Proc Indian Acad Sci Sect A, 89(1980)197] which uses the radiosonde data of nearby land stations. It is found that under clear weather conditions the temperature corrections thus estimated (using the radiosonde data) can be applied, to yield realistic SST values. up to distances as large as 500 km off the coast. In cases of strong weather conditions, such as depressions or cyclonic storms, these temperature corrections do not seem to be true representations even for distances as small as 50 km. The SST results of the air-borne experiment are in good agreement (within 1ᵒC) with the NOAA satellite derived sea surface temperatures.
