From: Rapid, accurate computation of narrow-band sky radiance in the 940 nm gas absorption region using the correlated k-distribution method for sun-photometer observations

Fig. 7

Angular distributions of simulated normalized radiances simulated for type 2 (Table 3) in the almucantar and principal planes with an FWHM of 10 nm and a central wavelength of 940 nm. a, b Convolved normalized radiance, \(R\). c, d Relative errors of the simulated radiance with the SN-CKD and WV-CKDs. SN-CKD is a standard lookup table for the CKD method in the radiative transfer model RSTAR. WV-CKD is a series of lookup tables for the CKD method in the water vapor absorption region of 940 nm at 2-, 5-, and 10-\({\mathrm{cm}}^{-1}\) intervals. Note that the lines in the top panels overlap
