I was wondering, does ESA provide a “Data Coverage”/“Data Coverage Percentage” variable in the metadata for Sentinel-2? In the .xml files? I am looking for an analogue to the “cloudcoverpercentage” variable that you get if you provide a OpenSearch query to e.g. scihub.
They have one in the database: http://sentinel-pds.s3-website.eu-central-1.amazonaws.com/.
