Description

The variable AOT (dimension-less) defines the column-integrated value of the vertical aerosol extinction coefficient at 550 nm. Typical worldwide and annual AOT values for satellite observations range from 0.05 to 0.4, with extreme values of 1 and typical mean values around 0.12 (default value).

This variable controls the strength of the absorption and scattering effects caused by aerosols.
