12 **Water Vapour **content from the L1C image. This algorithm uses a ratio between band B8A and band B09. It is therefore important to have a very good internal resampling that preserves the geolocation accuracy of bands that have different native resolution.

15 The main output of the Cloud Screening and **Scene Classification **module consists in a Scene Classification map. Together with the Scene Classification map, two quality indicators are provided: a Cloud confidence map and a Snow confidence map with values ranging from 0 to 100 ~(%).
