Question about the algorithm used by Sen2cor for atmospheric corrections

Hello everybody,

Please, I’m looking for the algorithm that is used by sen2cor to make atmospheric corrections ??
thank you in advance


according to this page:

SENTINEL-2 Atmospheric Correction (S2AC) is based on an algorithm proposed in Atmospheric/Topographic Correction for Satellite Imagery (ATCOR; Richter and Schlaepfer, 2011). The method performs atmospheric correction based on the LIBRADTRAN radiative transfer model (Mayer and Kylling, 2005).

These are:

  • Richter, R., Schlaepfer, D., and Mueller, A. “Operational atmospheric correction for imaging spectrometers accounting the smile effect’”, IEEE TGRS, Vol. 49, 1772-1780 (2011). PDF
  • Mayer, B., Kylling, A. “The libRadtran software package for radiative transfer calculations-description and examples of use”, Atmospheric Chemistry and Physics 5, 1855–1877 (2005). PDF
