SICOR - Sensor Independent Atmospheric CorrectionSensor Independent Atmospheric Correction of optical Earth Observation (EO) data from both multispectral and
hyperspectral instruments. Currently, SICOR can be applied to Sentinel-2 and EnMAP data but the implementation of
additional space- and airborne sensors is under development. As unique features for the processing of hyperspectral
data, SICOR incorporates a coupled retrieval of the three phases of water and a snow and ice surface property
inversion based on a simultaneous optimization of atmosphere and surface state (Bohn et al., 2020; Bohn et al., 2021).
Both algorithms are based on Optimal Estimation (OE) including the calculation of several measures of retrieval
uncertainties. The atmospheric modeling in case of hyperspectral data is based on the MODTRAN® radiative transfer code
whereas the atmospheric correction of multispectral data relies on the MOMO code. The MODTRAN® trademark is being used
