Calculating cloud coverage


I would like to ask you a couple of questions about cloud coverage:

  1. Do you calculate cloud coverage for L2A in the catalog service based on the geographic bounds (bounding box query) - or the cloud coverage percentage is pre-calculated for the scene and always constant?

  2. Do you know of any tool which is reporting for a given bounding box real cloud coverage in the scenes - based on the pixels marked as clouds only visible in the bounds of the query?

Thank you.

The catalogue service provides scene’s cloud statistics.
