day (center left), instrument status report list (center right), latest forecast summary (bottom center), and links to other reports (right). The IFloodS portal’s addition of a map-based data visualization capability offered a significant improvement over previous GPM GV field campaigns. This map feature supported a display of various types of spatial information, including IFloodS instrument locations and coverage areas, rivers and watershed boundaries, and roads and political boundaries

investigation. The D3R was deployed collocated with NASA’s S-band polarimetric radar (NPOL) during the NASA Iowa Flood Studies (IFloodS) field campaign as part of the GPM ground validation. Both D3R and NPOL were deployed in Traer, Iowa, from 1 May to 15 June 2013 to observe precipitation in concert with an array of ground instruments, NEXRAD S-band radars, and the University of Iowa’s X-band radars in the area of the Cedar River and Iowa River basins. During the field campaign, severe flooding was observed

std dev due to parameterization of various rainfall algorithms as a function of rainfall rate at S band. 3. Rainfall events and dataset description To demonstrate the performance of the aforementioned rainfall algorithms, S-band NPOL radar data collected during the IFloodS field experiment are used ( Wolff et al. 2015 ). During the IFloodS experiment, the NPOL radar was deployed at an ideal location to fill the gap of WSR-88D low-elevation coverage, and for proximity to local river basins. NPOL

important component of the Ground Validation (GV) program of the NASA Global Precipitation Measurement (GPM) satellite mission, IFloodS was one of the first field campaigns dedicated to hydrological studies. We extensively examine the two assumed advantages of the Iowa XPOL units—high spatial resolution and the ability to mitigate attenuation using multiple radars—herein using data collected during IFloodS. We deployed the XPOL-2 and XPOL-4 units with overlapping coverage over the Turkey River watershed

northeastern Iowa. NASA and the Iowa Flood Center (IFC) laid down a heavily instrumented network of rain gauges, disdrometers (2DVDs and Autonomous Parsivel Units), and micro rain radars throughout the IFloodS region. The Iowa XPOL radars were deployed in pairs in the Clear Creek and Turkey River Watersheds. The coverage of all XPOLs overlapped with that of NASA’s S-band polarimetric (NPOL) radar. Mishra et al. (2016) presented comprehensive polarimetric data analyses and comparisons of XPOL-2 and XPOL-4
