Air-monitoring raw light, UV band 2, fast (Copernicus)

Sentinel-5P Level 1 Radiance Band 2 (NRTI)
atmosphere ESA ESA Copernicus active
In plain English

What it measures. The raw spectrum of Earth's reflected and emitted light in spectral band 2, in the ultraviolet range. It holds calibrated brightness values, not a processed air-quality result.

How it's made. Acquired by the TROPOMI instrument aboard ESA Copernicus's Sentinel-5P satellite and released as Level-1 data in near-real-time for quick availability.

How & where you'd use it. Feeds the processing chains that generate ozone and other trace-gas products; on its own it is a technical input for specialists.
