Air-monitoring raw light, UV band 4, fast (Copernicus)

Sentinel-5P Level 1 Radiance Band 4 (NRTI)
atmosphere ESA ESA Copernicus active
In plain English

What it measures. The raw light spectrum from Earth in spectral band 4, in the ultraviolet range, held as calibrated brightness values rather than a processed result.

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

How & where you'd use it. A low-level input feeding the production of ozone and other trace-gas measurements; not directly usable without further processing.
