Multi year changes of Aerosol Optical Depth in the monsoon region of the Indian Ocean since 1986 as seen in the AVHRR and TOMS data
Aerosol Optical Depth (AOD) data based on AVHRR and TOMS was analyzed to find out the changes in the Indian Ocean from 1981 to 2004.Four regions covering Indian Ocean north of 10° S were studied in detail.The results strongly suggest that the mean value of AOD in these regions decreased from 1986–1990 MENS VESTS to 1995–1999.The Ara
