Although there are no good solutions for strict transformation of column broadband optical parameters from one solar elevation to another, multiannual pyrheliometric time series, recorded at various stations, mainly on the territory of the former USSR, have stimulated creation of corresponding semi-empirical methods.
Figure 7 compares the direct normal irradiance predicted by SMARTS and two flavors (1) of the historic ASHRAE radiation model to that of pyrheliometric measurements (obtained with either an absolute cavity radiometer or a first-class pyrheliometer).
