Abstract	:	The data from INSAT-IB geosynchronus satellite has been used to make maps of albedo, solar energy and temperature distribution over the Arabian Sea which includes the Pakistan's fifth province in the ocean. Visible data in the range of 0.55 to 0.75 mum and infrared data in the range of 10.5 to 12.5 mum have been used. Four months data were processed to show the different kinds of variation in ocean temperatures and the albedo. The months chosen were July 85, October 85, January 86 and April 86. In the month of July we have a large number of clouds over the Arabian Sea because of the monsoons, and it is very difficult to find a cloud free day in order to calculate the ocean temperatures. First the albedo maps were drawn for all four months and only three days for each month, which had no clouds or minimum number of clouds over the Arabian Sea were chosen. The minimum albedo and Solar Energy maps for all four months were drawn. For each month, three albedo and sea surface temperature maps were discussed in detail. For cloud free areas, sea surface temperature measurements appear to be reasonable when compared with monthly mean values obtained from sources other than INSAT IB. However, values calculated by using INSAT IB infrared data were found to be, in general, slightly lower than the monthly mean surface temperature values. This difference may be improved by fine tuning the coefficients which are used in the correction for atmospheric attenuation and zenith angle.
