Ordinary least squares estimates of the Pic coefficient ofported in the third column of Table III, and the associateported in the fourth column of Table III. The results arethat use the original cloudiness measure (SKCit) are quported. Regressions that replace the cloudiness measure wset to one when SKCit is less than one, to zero when SKCseven, and to minus one when SKCit is greater than seven lar results.
