    Abstract
    The sea surface air temperature is an important parameter required for computation of air-sea fluxes over oceans which at present cannot be directly measured from remote sensing. In the present article, an empirical approach is proposed to determine the sea surface air temperature from satellite derived sea surface humidity in the Indian Ocean. Using the insitu data on surface met parameters collected on board O.R.V. Sagar Kanya in the Indian Ocean over a period of 15 years, the relationship between the surface air temperature and surface humidity is analysed by fitting a polynomial between the two for different regions of the Indian Ocean in different seasons. Taking into account the variation in surface air temperatures, the Indian Ocean is split in 14 regions and polynomial relationships for each region is established. The RMS errors associated with computation of surface air temperatures for each region along with constants of polynomial equations are presented
