An Intensive Observation Period for the Integrated Precipitation and Hydrology Experiment (IPHEx), part of NASA’s Ground Validation campaign for the newly launched Global Precipitation Measurement Mission took place from May-June 2014 in the Smoky Mountains of western North Carolina. As part of the experiment, the National Severe Storms Laboratory’s (NSSL) mobile dual-pol X-band radar, NOXP, was deployed in the Pigeon River Basin (PRB). The purpose of this study is to evaluate the performance of different post-processing algorithms of NOXP data with the suite of observation platforms within the IPHEx domain. In addition, the impact of standard precipitation datasets (Stage IV gauge-corrected radar estimates, Multi-Radar/Multi-Sensor System Quantitative Precipitation Estimates, Tropical Rainfall Measuring Mission (TRMM) 3B42V7 rainfall, CMORPH, WRF, etc.) on the performance of the CREST hydrologic model at small basin scales in complex terrain will be examined. Hydrologic simulations using a version of CREST with a priori parameters were conducted in the three small catchments within the PRB previously studied by Tao and Barros (2013): the Cataloochee Creek Basin, the East Fork Pigeon River Basin, and the West Fork Pigeon River Basin.
