Cloud properties from space, near-real-time (Copernicus)

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

What it measures. Describes clouds in each satellite view, including details like how much cloud is present and at what height. These are technical inputs rather than a simple weather picture.

How it's made. Derived from the TROPOMI instrument on ESA Copernicus's Sentinel-5P satellite as a Level-2 product, available rapidly in near-real time.

How & where you'd use it. Mainly a supporting input: cloud information is needed to correctly interpret the satellite's air-pollution measurements, since clouds get in the way.
