Incoming shortwave solar radiation in a black spruce (Piceamariana (Mill.) B.S.P.) taiga forest at 65°45′ N was measured during four summers, in a clearing and beneath the forest canopy. The ratio of radiation received beneath the canopy to radiation received in the clearing varied from 0.33 to 0.60. Prediction of shortwave radiation in the clearing based on continuous measurements at a permanent site 35 km distant was feasible; however, on-site measurement of shortwave incoming radiation remains necessary for specific daily values.
