Figure 2.

For all network sizes, vertical profiles of the errors of the radiative fluxes and heating rates based on the neural network-predicted optical properties with respect to the radiative fluxes based on the optical properties from RRTMGP. Shown are the mean (solid) and twice the standard deviation (dashed) of the error, for the downwelling (a) and upwelling (b) longwave radiation, longwave heating rates (c), the downwelling (d) and upwelling (e) shortwave radiation and shortwave heating rates (f ). A zenith angle of 42^° and an albedo of 0.07 is used for the shortwave fluxes. (Online version in colour.)
