Derivation of the photometric flux of daylight from filtered measurements of global (sun and sky) radiant energy.


The study reported on here is a continuation of an earlier investigation by the same authors into the relationship between natural illumination and shortwave solar radiation. Whereas the initial approach treated the illumination of sunlight as derived from the corresponding filtered direct radiation component, the results now given extend this work to… (More)
