... were determined and presented in Fig. 6 . It was observed that χ contributes the most to the model's accuracy as the average RMSE increased from 7.4 lm/W to 12.5 lm/W. Such observation can be attributed to the importance of χ in the occurrence of Rayleigh scattering of solar radiation. Further...
