Daily direct solar plus sky radiation (global) was measured above the canopy and at the forest floor in 3 deciduous forest communities of Neotoma, a small valley in southcentral Ohio. The amount of daily global radiation at the forest floor was maximal during April and rapidly declined as the canopy closed. After canopy closure, and throughout the summer, the percent of total global radiation reaching the forest floor was constant for the mixed mesophytic and mixed oak communities; 10.1 percent for the mixed oak community, and 7.3 percent for the mixed mesophytic community. The percent of total global radiation reaching the forest floor of the ridgetop chestnut oak community was much greater, averaging 26.5%, and more variable.
