atmosphere ESA ESA Copernicus active
In plain English

What it measures. Shows how much methane is present in the atmosphere, mapped at high spatial detail worldwide.

How it's made. Built from TROPOMI observations on ESA Copernicus's Sentinel-5P satellite as a Level-2 offline product, processed for better accuracy than the rapid version.

How & where you'd use it. Used to locate and quantify methane emission hotspots and to track this greenhouse gas for climate and environmental policy.
