Sulphur dioxide pollution maps, refined (Copernicus)

Sentinel-5P Level 2 Sulphur Dioxide (OFFL)
atmosphere ESA ESA Copernicus active
In plain English

What it measures. Shows where and how much sulphur dioxide gas is present in the air, a pollutant from industry, power plants, and volcanoes.

How it's made. Produced from the Sentinel-5P satellite at Level-2 in an offline version, processed a bit later for improved quality.

How & where you'd use it. Helps map industrial emission sources, study acid rain, and track volcanic plumes over time.
