threshold=float: Minimum ESA cloud percentage to trigger cloud and shadow detection.; Default: 0
output_clouds=string [required]: STRDS with cloud masks of Sentinel-2 scenes
min_size_clouds=float: Value option that sets the minimal area size limit (in hectares) of the clouds
output_shadows=string: STRDS with shodow masks of Sentinel-2 scenes
min_size_shadows=float: Value option that sets the minimal area size limit (in hectares) of the cloud shadows
