Atmospheric aerosols are considered to be one of most complex and important parameter affecting the climate change. According to IPCC Scientific understanding of Atmospheric Aerosol forcing on climate change is very low. Estimating the impact of Atmospheric Aerosols on climate is very complex as they differ in chemical composition and optical properties viz. Scattering and absorbing. Precipitation phenomena is influenced by aerosols hence study of atmospheric aerosols over Indian sub continent is necessary as the Indian economy is highly dependent on Monsoon rainfall. AOD (Aerosol Optical Depth) from MODIS (MODerate Resolution Imaging Spectroradiometer) onboard Terra and Aerosol Index (AI) from OMI (Ozone Monitoring Instrument) onboard Aqua to study the seasonal variation of Aerosols. Study of Aerosols during Monsoon is highlighted to investigate their behaviour during this season. Aerosol loading is found to be more in the study region during Monsoon(June, July, August, September) and less in Post monsoon (October, November). Effect of Topography on Aerosol loading is observed and Aerosol loading is less over elevated regions. The COV (Coefficient of Variation of AOD is high over elevated regions showing high variability. High Aerosol Index over Arabian Sea and western India, and wind direction during monsoon indicates high aerosol loading transported through westerlies. This also supports the statement that the high values of AOD is not due to cloud contamination but due to presence of high amount of Aerosols and most of them are found to be transported from Arabian desert and Africa through Arabian sea.
