The GPM Ground Validation Iowa Flood Center (IFC) Stream Flow IFloodS dataset was obtained from the IFC during the Iowa Flood Studies (IFloodS) field campaign that extended from March 31, 2013 through June 30, 2013. The main goal of IFloodS was to evaluate how well the GPM satellite rainfall data can be used for flood forecasting. The IFC monitors stage levels using sensors attached to the side of bridges throughout Iowa. The sensor data are downloaded from the Iowa Flood Information System (IFIS) as support data for the IFloodS campaign. The IFC Stream Flow data were collected in real-time and provide measurements at 15 minute intervals. These IFC Stream Flow IFloodS data are available in XML format.
