[GIS] Sentinel 2A L1C product convertion from TOA reflectance to BOA reflectance

atmospheric-correctionreflectancesentinel-2

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

Is there an equation?

Best Answer

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.
