Aerosol Optical Thickness

Aerosol Optical Thickness

The Aerosol Optical Thickness (AOT) product is derived from Himawari-8/9 visible and near-infrared data. It provides information on aerosol optical thickness at 500 nm and the Angstrom index (a metric of aerosol particle size) for areas over oceans during the daytime and on aerosol optical thickness over land. The algorithm references a look-up table with values calculated on the basis of an assumed spheroid-particle aerosol model. The AOT product can be used to monitor Aeolian dust events.
