GPM Ground Validation USGS Stream Flow IFloodS V1

The GPM Ground Validation USGS Stream Flow IFloodS dataset was obtained from USGS during the Iowa Flood Studies (IFloodS) field campaign that extended from March 30, 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 USGS monitors streamflow using gauges on streams and rivers throughout the U.S. For the IFloodS field campaign, streamflow data from about 200 gauges in the Iowa IFloodS study area were downloaded from the USGS web site as support data for the campaign. The USGS streamflow data were collected in real-time and provide measurements at 15-60 minute intervals. These USGS Stream Flow data are available in XML format.

该GPM地面验证美国地质调查局河流流量IFloodS数据集系在2013年3月30日至2013年6月30日进行的爱荷华洪水研究（IFloodS）野外考察期间，从美国地质调查局（USGS）获取。IFloodS项目的主要目标在于评估GPM卫星降水数据在洪水预报中的应用效果。美国地质调查局通过遍布美国各河流与溪流的流量计来监测河流流量。在IFloodS野外考察期间，约200个流量计在爱荷华IFloodS研究区域的流量数据已从USGS网站下载，作为考察的支持数据。这些USGS河流流量数据系实时收集，并按15至60分钟的时间间隔提供测量值。该USGS河流流量数据以XML格式提供。
