PRISMA/GRASP Processing Results

PRISMA/GRASP results processed with 3 different retrieval configurations:

1.     v1 (“v1_wo_clim”): the Sentinel-5p TROPOMI/GRASP aerosol type climatology (i.e. 60% urban - fine non-absorbing; 10% oceanic; 30% dust) is used universally for all PRISMA scenes and the surface is treated as isotropic.

2.     v2 (“v2_w_clim”): the monthly 2-degree spatial resolution Sentinel-5p TROPOMI/GRASP aerosol type climatology is used and the surface is treated as isotropic.

3.     v3 (“v3_w_clim”): both the monthly 2-degree resolution Sentinel-5p TROPOMI/GRASP aerosol type climatology and the climatology for the volumetric and geometric surface “BRDF2” and “BRDF3” parameters from TROPOMI/GRASP are used.
