The screen is made of l/4-inch galvanized hard- ware cloth enclosed in a stout wire ring slightly smaller than the diameter of the pan. It prevents interception of a portion of the solar energy dur- ing the day and decreases back radiation at night, thus maintaining a more uniform water temperature than would exist without the screen. This pan was developed by Arthur A. Young of the United States Department of Agriculture in cooperation with the California State Division of Water Resources, Bureau of Plant Industry Pan This pan is made of 22-gauge galvanized iron, 6 feet in diameter, 24 inches deep, set 20 inches in the ground with the water surface in the pan at ground level. Because this pan is set in the ground and contains a greater volume of water than the V-Jeather Bureau pan, its water temperatures are cooler during the day and warmer during the night. Consequently, evaporation is lower than from the more exposed pan. Square Floating U. S. Geological Survey Pan This pan is made of 18-gauge galvanized iron, 3 feet square and I-I/2 feet deep. It is supported either by a raft or two metal cylinders so placed that the surface of the water in the pan coincides with the-.-r surface of the reservoir. Evaporation Coefficien ts Evaporation from pans with small water surfaces is greater than the loss for larger areas. It is common practice to apply a coefficient to pan evaporation to estimate that occurring from an adjacent lake or reservoir. The ratio of evaporation from a given type of pan to evapo- ration from a larger body of water is designated as an evaporation coefficient. It is variable according to the integrated effect of the meteorologic factors on different pan«. Coefficients obtained as the results of research studies in California^/, Colorado^/, and Oklahoma^/ are useful for conversion of measured evaporation from a small pan to equivalent evaporation from a lake or reservoir. Table 1 shows evaporation coefficients for several pans used in California and other western states. \J Evaporation From Water Surfaces in California by Arthur A. Young.
