Air-monitoring raw light, UV band 1, offline (Copernicus)

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

What it measures. Calibrated raw light measurements from Earth in ultraviolet spectral band 1. This is upstream sensor data rather than a ready-to-read map of any single quantity.

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

How & where you'd use it. Used by atmospheric scientists as the starting material for deriving pollution and trace-gas products; it is a technical input, not a public-facing dataset.
