The spectral power distributions of daylight from the north sky at Tokyo Institute of Polytechnics, Atsugi in the medium latitude region were measured by using an automatic spectro-radiometer in the period of four years (1989 to 1993) in order to investigate the applicability of the CIE daylight data. The principal component analysis was applied to the spectral power distributions of daylight measured in the period of three months (January 1991 to March 1991), and the first and second contribution factors became 98.3 percent. The reconstituted distributions of daylight at Atsugi had quite a good agreement in comparisen with those of CIE in the visible spectral range, but had lower values in the ultra violet spectral range.
