WitrynaPOSSIBLE APPROACH. Atmospheric correction consists of retrieving of Lw ( λ) from the sum L a ( λ) + t ( λ )L w ( λ) = L t − L r, as assumed by (1). Usually, it is assumed that L w = 0 for λ > 750 nm ; therefore, in the case with only the first eigenvector, the problem is reduced to solving of an equation in one unknown c a1.
