摘要
The role of aerosols in weather and climate processes over the Asian Region is one of the important scientific problems. Space based observations are the main source of quantitative information on aerosols and their variability over large areas. In the present study 18 years of TOMS Monthly Mean Data on Aerosol Index, and 6 years of MODIS Optical Depth data at 550nm were analyzed. The spatial and temporal distribution was examined for all the months over the Indian Sub-continent and adjacent Indian Ocean. Mean monthly aerosol distribution is described in detail. Temporal variations are described using separate monthly charts for the North West, North East, Western Equatorial and Eastern Equatorial Indian Ocean for all the years.
