Description: Measurements indicate a relation between diurnal curves of relative humidity and moisture content of some important fuels of Oregon and Washington. Some of these measurements were made in early years of forest fire research in this region. The data in this note were collected at intervals throughout 4 days (in September 1938) at the Wind River Experimental Forest near Carson, Wash. The relations presented here will be of interest when the new National Fire Danger Rating System is used in the Pacific Northwest. This system bases its estimate of fine-fuel moisture content on relative humidity measurements.
