The University of Minnesota climatological observatory on the St. Paul campus has been in the path of four partial eclipses, ranging from 500/4 to 91 % of totality (the area of the covered sun) since operations began in 1960. Three of the four partial eclipses occurred while the atmosphere at St. Paul was essentially cloud-free. Measurements made during the three partial eclipses include incoming and reflected solar radiation, incoming and outgoing longwave radiation, air and soil temperatures, relative humidity, and wind speed and direction. Of the partial eclipses for which the effects could be measured, only the one of 30 …
