The correction effect of Sentinel-2 L2A

Hi community,

The L2A image of Japan on April 23, 2022 was displayed in EO Browser and the cloud areas were pink or yellow as shown below.

Do you know what causes this phenomenon?

When processing large amounts of data in a Python script, is there a possibility that mixing such data could cause problems?

Hi Aoi,

This effect looks like an error in the Atmospheric Correction performed during the conversion from L1C to L2A (with sen2cor). In the L1C product the phenomenon is not visible: https://sentinelshare.page.link/LnpS

If this causes problems in your processing, I would suggest you contact Copernicus support with this issue: eosupport@copernicus.esa.int.
