Air-monitoring raw light, UV band 3, offline (Copernicus)

Sentinel-5P Level 1 Radiance Band 3 (OFFL)
atmosphere ESA ESA Copernicus active
In plain English

What it measures. Calibrated raw light measurements from Earth in ultraviolet spectral band 3. It captures sensor readings ahead of any pollution calculation.

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. Serves as routine input for the atmospheric products derived later; intended for processing pipelines rather than direct interpretation.
