heterogeneous suite of scans for testing various engineering capabilities of the radars and cross validation with other instruments. The radars made polarimetric observations at multiple range resolutions (75 and 30 m) with oversampled range spacings of 75, 30, 15, and 7.5 m. These data were collected at the scan rate of 5° s −1 in both plan position indicator (PPI) and range–height indicator (RHI) scans. We had enabled the clutter filters in the XPOL signal processors during the IFloodS data collection

NPOL are compared using a plan position indicator (PPI) scan for 1.4° elevation at 2248 UTC 29 May 2013. The results are presented in Fig. 8 . The figure compares a D3R Ku band and an NPOL PPI scan of heavy convection embedded in stratiform rain observed at the same elevation and same time. Four radar measurements are considered: , , , and copolar correlation . Attenuation correction is applied to the observations of reflectivity and differential reflectivity presented here. Fig . 8.

was operated in several modes, including the two-sweep (i.e., 0.7° and 1.4°) full plan position indicator (PPI), RHIs over the APU disdrometers, PPI sector (PPS) scans of precipitation systems over principal river basins, and “bird bath” scans that can be used for monitoring Z dr biases. The RHI sector scans covered an azimuth range of 8° above locations of ground-based instrumentation (e.g., APU disdrometers). The PPI and RHI scan tasks were repeated once every 3 min when precipitation was

the Clear Creek Watershed. The XPOL-5 operated at range resolution of 75 m and scanned over the watershed (90°–310° sector) at the rate of 5° s −1 for both plan position indicator (PPI) and range–height indicator (RHI) scans. When targets of opportunity occurred within the XPOL-5 coverage, its scan sequence was as follows: a low-elevation full PPI surveillance scan at 5° s −1 , sector PPI scans at 5° s −1 over the watershed sector in elevations from 2° to 8° in increments of 1°, a birdbath
