The implemented EnKF framework generates an optimal albedo estimate (\(\hat{\alpha}\)) between the CRHM modelled (\(\alpha_{m}\)) and Sentinel-2 observed (\(\alpha_{o}\)) albedo by weighing the modelling (\(\sigma_{m}^{2}\)) and measurement error variance (\(\sigma_{o}^{2}\)) using the Kalman gain (\(K\)),
