@panoramajuerg As explained by @Gkikas-LGPZ, there are areas showing rain and the color scale gives the amount of precipitation in these areas. To know the cloud cover in % you must use the weather picker. But if you want to get the cloud cover scale, see Menu > Settings > Customize layers colors > Select overlay > Clouds [image: 1565254493423-b415a00d-75e5-46ca-997b-911877d3d4d1.jpeg] Note there is a mistake in this scale: you should read % instead of mm. Personally I have modified this color scale to avoid the dark grey used for 30% cover and with more details.
