SUMMARY Solar radiation was measured for 19 months at 10 sites in the Pentland Hills, an area 20 km by 17 km to the south of Edinburgh. Singular value decompositions of the data matrix of monthly means, with and without subtraction of row and/or column averages, revealed the pattern of variations. A reduced rank regression model was used, which related site weightings in the decomposition to physical characteristics of the sites.
