Data are presented from a mesoscale network of integrating pyranometers established in Wisconsin, for the period December 1966 through June 1967. The data have been normalized so that they are expressed as a percent of the clear day global radiation values. The monthly values for the percent of the clear day global radiation received over the State, ranged from 72.3 to 58.4 percent. For the 7 months examined, the gradients across the State ranged from 5.5 to 12.8 percent of the possible global radiation. Maps of the monthly distribution patterns have been presented. These have been interpreted in the light of the prevailing weather systems.
