Fig. 3From: Rapid, accurate computation of narrow-band sky radiance in the 940 nm gas absorption region using the correlated k-distribution method for sun-photometer observationsThe maximum error of the SN-CKD with CA-DB. SN-CKD is the standard lookup table for the CKD method in the radiative transfer model RSTAR. CA-DB is dataset consisting of radiances at ground level under continental averaged aerosol condition of Hess et al. (1999)Back to article page
