Climatic data for Williams Lake, Hubbard County, Minnesota, 1986
D.O. Rosenberry, A.M. Sturrock, T. C. Winter
1988, Open-File Report 88-304
Research on the hydrology of Williams Lake, north-central Minnesota includes study of evaporation. Presented here are those climatic data needed for energy-budget and mass-transfer studies, including: water-surface temperature, dry-bulb and wet-bulb air temperatures, wind speed, precipitation, and solar and atmospheric radiation. Some calculated values necessary for these studies, such as...
