This product provides the above cloud aerosol optical thickness, the Angström exponent, the aerosol single scattering albedo, the cloud optical thickness corrected for the effect of the overlapping absorbing aerosol and the instantaneous aerosol above cloud forcing in W.m-2. This product is given at a resolution of 6´6km2.
All variable with the prefix “AAC” and/or with the suffix “absorption_corrected” in the name belongs to this product.
This product is only available over dark ocean and over some dark land surfaces.

Recommendations: This is the best product in terms of accuracy in order to evaluate climate models (Peers et al., 2016, GRL) or to investigate the effects of above cloud aerosols on clouds properties (Deaconu et al., 2019). We recommend to use one additional quality filter, as described below.
