The physical skylight model has a cloudiness modulator (fudge factor). This parameter is currently optimized, considered floating. Using additional information such as climate fields and near surface radiation estimates one could constrain positions better, excluding certain positions due to suppression of daytime values - although additional calibration might be needed (similar to current protocols).
