2. Comparisons of different band options show that the 5-band scheme used by SNICAR effectively captures the spectral variation of snow albedo and therefore produces more accurate solar flux estimation for snow-covered sea ice. The left figure shows spectral snow albedo and band-averaged albedo for different options. The right figure shows the error of reflected shortwave flux computed using different band approximations, evaluated against the spectrally integrated reflected solar flux from 0.3 to 5 microns for every 10 nm. Proposed new model results for snow-covered sea ice are those shown for RRTMG-MergeSNICAR.
