Abstract :
Aerosol optical thickness (AOT) and size parameters are among the main atmospheric parameters retrieved from the MODIS instrument on board the Terra satellite. We have embarked on a massive effort to validate these aerosol products globally, by cross correlating MODIS spatial statistics with ground-based AERONET temporal statistics. This has produced good validation in various parts of the Earth both over land and over oceans. The validation statistical data are generated daily and are available to the science community for short and long term studies in various parts of the earth for the lifetime of MODIS
