AB: Successful ground validation of rainfall, microphysical, and heating products from the Global Precipitation Measurement (GPM) core and constellation satellites will rely on a multi-faceted combination of many ground-based instruments at land and ocean "Supersites", as well as possible constellation validation sites. The FRPP, held along northern Colorado's Front Range during May-July 2004, provided a low cost opportunity to demonstrate the valuable, synergistic combination of dual-frequency, dual-polarization scanning Doppler radars (CSU-CHILL S-Band and NOAA-ETL X-Band), dual-frequency profiling radars (AL and ETL profilers at the Platteville and Boulder Atmospheric Observatories), surface disdrometers (ETL and AL Joss-Waldvogel and CSU's 2D-Video) and rain gauges. The program had three main objectives: (1) Dual-wavelength dual-polarization scanning radar DSD and rain rate estimate intercomparison, validation, and error characterization, (2) Dual-wavelength profiler demonstration in the Supersite concept, and (3) Rain rate and drop size distribution characterization in the context of Supersite observations and rainfall regimes. This poster will show results from the FRPP, in the context of both case studies demonstrating the advantages of planned Supersite instrumentation, and demonstration of case study composites separated into regimes according to their rain type and environmental characteristics. A template and preliminary demonstration of error analysis for GV data will also be presented, which will allow quantitative measurement uncertainties to be propagated from particular GV instrumentation to the satellite pixel resolution.
