Interpretive Summary:

Technical Abstract: A long term in situ network for the study of soil moisture and precipitation was deployed in north central Iowa, in cooperation between USDA and NASA. A total of 20 dual precipitation gages were established across a watershed landscape with an area of approximately 600 km2. In addition, four soil moisture probes were installed in profile at 5, 10, 20, and 50 cm. The network was installed in April of 2013, at the initiation of the Iowa Flood Study (IFloodS) which was a six week intensive ground based radar observation period, conducted in coordination with NASA and the University of Iowa. A variety of quality control procedures are examined and spatial and temporal stability aspects of the network are examined. Additionally, in the summer of 2014, large scale field sampling was conducted to determine network accuracy. Initial comparisons of the watershed to soil moisture estimates from satellites are also conducted.
