Minimize Aerosol Optical Thickness

The aerosol optical thickness (or depth) is one of the variables included in the w_aer.nc file. The other is the aerosol Angström exponent.

The following table provides the main characteristics of this variable including coverage, parameter ID, time latency, sampling and bands used in the associated product. The ancillary and auxiliary data provides the variables used during processing and are provided in Auxiliary Data Files (ADFs).
