NWS Daily Climatology Data: 1983 (SNF)

Weather data were collected by the National Weather Service in International Falls, Minnesota. International Falls is about 80 miles from the SNF, but the weather data is representative of the area. Total solar insolation measurements were made at Fall Lake Dam in Winton, Minn. by Prof. Donald Baker of the Department of Soil Science at the University of Minnesota, St. Paul. Insolation values were measured using a Yellow Springs solar cell calibrated against an Eppley Pyranometer.

气象数据由美国国家气象局（National Weather Service）于明尼苏达州国际瀑布城采集。该市距离SNF约80英里，但所采集的气象数据可代表该区域的气候特征。总太阳辐射量（Total solar insolation）数据由明尼苏达大学圣保罗分校土壤科学系的唐纳德·贝克教授，于明尼苏达州温顿市的福尔湖大坝测得。辐射量数值通过经埃普利总辐射表（Eppley Pyranometer）校准的黄泉（Yellow Springs）太阳能电池进行测量。
