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

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

What it measures. Raw, calibrated light spectra from Earth in ultraviolet spectral band 1. These are foundational sensor readings rather than a finished measurement.

How it's made. Collected by the TROPOMI instrument on ESA Copernicus's Sentinel-5P satellite and reprocessed at Level-1 with improved, consistent calibration applied to the full archive.

How & where you'd use it. Provides a consistent, reprocessed baseline for long-term studies that re-derive atmospheric products; an input dataset rather than an end product.
