Air-monitoring raw light, visible band 5, fast (Copernicus)

Sentinel-5P Level 1 Radiance Band 5 (NRTI)
atmosphere ESA ESA Copernicus active
In plain English

What it measures. Earth's measured light spectrum in spectral band 5, recorded as calibrated brightness values rather than a finished pollution measurement.

How it's made. Observed by the TROPOMI instrument on ESA Copernicus's Sentinel-5P satellite and delivered as Level-1 data in near-real-time.

How & where you'd use it. Acts as raw input for the algorithms that derive trace-gas and aerosol products; a building block, not a standalone map.
