Problem in Calibration for sentinel 2

dear everyone,

  I want to do the calibration step for sentinel 2 data , but I cannot obtain the offset and gain values for each band, does anyone has the file for clibration or any ideas???

Many thanks


to obtain the reflectance from a Sentinel-2 L1C product, you have to divide the DN by the QUANTIFICATION_VALUE, which you can find in the product metadata (it should be 10000). If you open the S2 product using SNAP, the pixel value should be directly the reflectance, as this division is made automatically by SNAP.

thank you for your suggestions
