Water vapour is one of the major components in the atmosphere with strong impacts on the earth's climate and weather. Water vapour absorbs radiation in the infrared spectral range and its abundance in the atmosphere, making it the most important natural greenhouse gas.

The Total Column Water Vapour (TCWV) generated by S5P-PAL is a pre-operational TROPOMI product. In contrast to other satellite sensors, TROPOMI provides daily global measurements of TCWV over land and ocean.
