How can I convert the TOA reflectance values of L1C Sentinel2A products to BOA (Bottom Of Atmosphere) reflectance values?

Is there an equation?


You'll need to run ESA's Sen2Cor algorithm to process Sentinel-2 Level-1C data to Level-2A.

This will give you atmospherically corrected BOA data. If you then divide the values by the quantification value (10000) you'll end up with BOA reflectance data.
