Sentinel-2 L2A from Sen2Cor does not match values of downloaded S2 L2A

[ABraun]

what makes you think that the corrected values are wrong? It is not unlikely that low values will be corrected?

Please note that the rasters are stored as integers and have to be divided by 10000 to get the true reflectance. Please have a look at these topics.

• Are S2 Level 2A products pixel values reflectance?
• The QUANTIFICATION_VALUE has a true value (DN to TOA Reflectance)?
• Quantification_value 1000?
• Extract the quantification values from L2A Sentinel-2
• Comparison between jpg2000 and xml files for Sentinel 2A
