New! ISU Soil Moisture Network
The Soil Moisture Network uses a non-heated tipping bucket rain gage and is unable to measure snowfall. If you are interested in higher quality precipitation data, check out the NWS COOP network of human observations.
Legacy ISU AgClimate Network
The Iowa State University "Ag Climate" network is one of the nation's oldest automated weather observation networks with data dating back to 1986. These stations are scheduled to be removed during the spring of 2014.
