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

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

What it measures. Calibrated raw light readings from Earth in spectral band 5. This is sensor data captured before any atmospheric quantity is computed.

How it's made. Recorded by the TROPOMI instrument on ESA Copernicus's Sentinel-5P satellite, processed to Level-1 in standard offline mode.

How & where you'd use it. Used as routine input for downstream air-quality products; intended for processing pipelines rather than direct reading.
