Absolute Error Estimation of the RACE Atmospheric Correction Module Based on Space Images From the Sentinel‑2 Satellites

The article discusses two atmospheric correction modules: RACE (A Robust Atmospheric Correction Procedure) and Sen2Cor of the Earth observation satellites “Sentinel‑2” (ESA) (image processing level: L2A) and their quantitative comparison. The RACE module processed 22 Sentinel‑2 scenes with the L1C processing level, various shooting conditions and a wide variety of objects. The average absolute error for all scenes in the derived albedo ranges was estimated for each of the 22 scenes for the B2, B3, B4 and B8 Sentinel‑2 spectral channels. As a result of the RACE absolute error estimation for the spectral channels considered, it was shown that the RACE module was comparable in the albedo determination accuracy at the Earth’s level to the Sen2Cor module.
