Cloud parameters, standard processing (Copernicus)

Sentinel-5P Level 2 Cloud (OFFL)
atmosphere ESA ESA Copernicus active
In plain English

What it measures. Provides cloud characteristics such as coverage and height for each measured scene, expressed as technical parameters.

How it's made. Comes from TROPOMI on ESA Copernicus's Sentinel-5P satellite as a standard Level-2 offline product, processed with extra care for accuracy.

How & where you'd use it. Chiefly used as a correction layer so that gas measurements (like NO2 or ozone) are not thrown off by clouds; a low-level input rather than a finished map.
