GOES-R Research - Validation with MODIS Aerosol Data

The ABI aerosol algorithm is being routinely run globally with MODIS reflectances as input proxy data for ABI. The resulting aerosol retrievals are also routinely compared to the standard MODIS Collection 5 aerosol products. Global maps of the two (ABI and MODIS) aerosol optical depth (AOD) products, fine mode weight and their differences are generated. In addition, bias and root mean square differences are calculated, and scatter diagrams of ABI vs. MODIS AOD, and bias as functions of solar and view zenith angles, and scattering angle are plotted. Examples of comparisons are shown below.

The images and scatter diagrams are available here. (Please note that access to this validation site requires an user id and password.)
