It appears as though there is a contradiction between the set of bands that are available for Sentinel-2-L2A in its documentation: Documentation - Sentinel-2 L2A and the bands that are used in the evalscript for the Statistical API example (Examples of Statistical API).
In the statistical API example, it uses the band “CLM”, but that is not listed anywhere in the Sentinel-2-L2A documentation. Why is this?
Where is “CLM” documented?
