Oak Lake Climate (1994 to 2005)

Field station staff work collaboratively with the National Weather Service in Sioux Falls, SD.  Air temperature and precipitation are measured daily using automated equipment to provide a long term climate record for the site. In addition, automated monitoring equipment has been installed to provide wind speed, wind direction and air temperature at 10m, 30m and 40m elevations above the ground.  Listed below are the average monthly precipitation and air temperature values recorded over the period 1994-2002. Complete data for our monitoring sites are available upon request from the Oak Lake Weather and Climate data page.
