St. Paul Campus Climatological Observatory

The University of Minnesota's Department of Soil, Water, and Climate maintains a Climatological Observatory on the grounds of the University's St. Paul campus. This page provides links to charts that show the last three days of weather data collected at the Observatory. These charts are updated each hour. The new charts should be available by about 15 minutes after the top of the hour.
