Abstract: Seasonal and spatial variations of reflected short wave, emitted long wave and net flux, along with albedo, at top of the atmosphere over India region have been examined. The analysis has been carried out using long term satellite observations from CERES onboard Terra, for a period of 18 years from March 2000 to February 2018. Reflected shortwave flux, net flux and albedo at the top of the atmospheres are observed to be highest during southwest monsoon (June-September), over most of the regions of Indian landmass and surrounding oceanic regions. Whereas, emitted longwave flux at top of the atmosphere is observed to be highest in pre-monsoon, over most of the land regions, and lowest in southwest monsoon. Seasonal and spatial variations of TOA fluxes and albedo are observed to be affected mainly by the variations in the cloud cover region in different seasons.
