An automatic spectroradiometer has been developed. Spectral measurements of the direct solar irradiation and of the angular dependence of the diffuse radiation are performed. The spectral range is 400 - 2300 nm with a resolution varying from 8 to 80 nm. The direction is selected by a scanning mirror/collimator system. Grating monochromators are used with Si and PbS photon detectors. The whole system is built into a caravan and intended for continuous operation. Based on long term time series from this instrument, detailed statistical models of the radiation are developed.
