The Cloud base layer is described in this post
“ Cloud base: Cloud base height is the altitude of the lowest cloud base above the ground, especially important for pilots. The model of terrain is simplified, so be cautious to use these values in the mountains. On large areas, the forecast model is not able to calculate the cloud base.”
