TROPOMI Level 2 Cloud Fraction, Albedo, Top Pressure Products in NRT - Sentinel-5P

"ROCINN algorithms have been employed as cloud retrieval algorithms based on measurements in and around the O2 A-band at 760 nm for the GOME-family of sensors. For S5p, the initial cloud-free composite is based on GOME-2 and OMI. Both CAL (""Clouds-As-Layers"") and CRB (""Clouds-as-Reflecting-Boundaries"") models are included. CAL is the preferred method for the relatively small TROPOMI/S5p ground pixels (7.5 x 3.5 km2)
