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

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

What it measures. Raw, calibrated spectra of light from Earth in ultraviolet spectral band 2. These are base sensor measurements rather than finished results.

How it's made. Gathered by the TROPOMI instrument on ESA Copernicus's Sentinel-5P satellite and reprocessed at Level-1 with uniform calibration across the mission archive.

How & where you'd use it. Supports long-term, consistent reanalysis of air-quality and trace-gas trends; an upstream input for researchers.
