@Daniel-Adam CO layer on Windy is provided by NASA Terra satellites. The satellite sensors measure the CO concentration and allow to visualize the areas where there is a higher concentration. But the satellite is not able to identify the origin. On its part Windy does not interpret data and thus cannot give more details about CO sources.
