Short summary
Water vapour (WV) is a key ingredient in virtually all meteorological processes. We present an algorithm which uses observations of the Flexible Combined Imager (FCI) to estimate the total column of WV (TCWV) over sun-lit, clear-sky pixels. FCI is a satellite instrument, and every 10 min it takes an image which covers Europe, Africa, and the Atlantic with a resolution of 1 km. Such high-resolution WV fields will provide valuable information for weather forecasters and researchers.
