Using data from the Copernicus Sentinel-5P satellite, this animation shows global methane concentration in the atmosphere in 2020.  

Methane is the second strongest greenhouse gas and its concentration in the atmosphere is currently increasing at a rate of around 1% per year. It absorbs heat from the Sun, more so than carbon dioxide, and contributes significantly to the warming of the atmosphere. As a result, there is a growing demand to track and regulate methane emissions.
