... of Rayleigh scattering of solar radiation. Further scrutiny shows that the contribution of the other variables is very close, and these ranged from 7.8 (i.e., D f ) to 7.6 lm/W (i.e., VIS, SH, and Δ). Just like χ, D f has been regarded as one of the most appropriate sky indicators for describing...
