Calculating cloud coverage

Hi,

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.
To do AOI based cloud filtering check this FAQ:

What is the best way to do cloud filtering at a specific AOI?
