AB: A new Multi-Angle Implementation of Atmospheric Correction (MAIAC) algorithm has been developed for processing of MODIS measurements. MAIAC is a generic algorithm which simultaneously retrieves the aerosol optical thickness and surface bi-directional reflectance using the 16-day time series of gridded MODIS L1B measurements over land. The new algorithm is generic and works globally over all surface types, including bright deserts, with the temporary exception of snow. MAIAC products include cloud mask, water vapor, aerosol optical thickness at 0.47 mm and 0.66 mm and Angstrom parameter, surface spectral bidirectional reflectance factor and albedo for the reflective land and ocean MODIS bands. All products are generated uniformly at 1 km resolution in gridded format. The initial comparison of the aerosol optical thickness with AERONET measurements for different types of aerosol, including urban/continental (USA, Europe), biomass burning (Africa, Brazil), dust (Saudi Arabia, China), shows a very good agreement.
