Abstract :
Twenty seven years (1983-2009) of International Satellite Cloud Climatology Project (ISCCP) cloud data and nine years (2001-2009) of Clouds and the Earth’s Radiant Energy System (CERES) top of atmosphere cloud radiative forcing data have been used to study the spatial distribution of clouds and the radiative forcing exerted by them over the Indian summer monsoon region. During the Indian summer monsoon season of June – September, cloud cover amount and cloud optical depth are more over the India and the adjoining Bay of Bengal region when compared to other seasons. Cloud top temperature of these monsoon clouds are lower (i.e., taller) in summer season when compared to other seasons. CERES data suggest that monsoon clouds exert a net cooling effect (net cloud radiative forcing is negative) which is uncommon over the tropical deep convective regions.
