Tropospheric ozone, reprocessed satellite record (Copernicus)

Sentinel-5P Level 2 Tropospheric Ozone (RPRO)
atmosphere ESA ESA Copernicus active
In plain English

What it measures. Measures ground-level ozone across the troposphere, the breathable layer where this gas is an air pollutant tied to respiratory problems and crop damage.

How it's made. Generated from the Sentinel-5P satellite at Level-2, in a reprocessed version where the whole archive is reworked with consistent methods.

How & where you'd use it. Good for long-term, consistent studies of air pollution and for research that compares conditions across many years.
