Do i have to transform Level 2A products into radiance

[ABraun]

as your data is stored as integers, you need to divide each value by the QUANTIFICATION_VALUE. 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
