Iowa Campbell Automated Weather Station Data

The data are a regional data set gathered primarily to support agriculture and agricultural research in Iowa. The data are from Campbell automated weather stations at Iowa State University sponsored research farms. In addition to the normal meteorological data listed, some additional derived variables are included, such as growing degree days and potential evapotranspiration. Current and historical daily and hourly data are available on the web site. Note that precipitiation is useful only during the growing season since a tipping bucket rain gauge is used at each site. The High Plains Climate Center provides the error checking and data transfer in support of their database.
