GPM Ground Validation NASA S-Band Dual Polarimetric (NPOL) Doppler Radar MC3E Table of Contents
The NASA NPOL radar, developed by a research team from Wallops Flight Facility, is a fully transportable and self-contained S-band (10 cm), scanning dual-polarimetric, doppler research radar that collected and operated nearly continuously during MC3E. NPOL scanned in high resolution RHI mode and provided measurements of precipitation in liquid, mixed and ice phase. The scanning strategy emphasized vertical structure sampling via RHI and narrow sector-volume data collections. Data was collected from 11 April 2011 through 03 June 2011. CampaignThe Midlatitude Continental Convective Clouds Experiment (MC3E) took place in central Oklahoma during the April-June 2011 period. The experiment was a collaborative effort between the U.S. Department of Energy (DOE) Atmospheric Radiation Measurement (ARM) Climate Research Facility and the National Aeronautics and Space Administration's (NASA) Global Precipitation Measurement (GPM) mission Ground Validation (GV) program. The field campaign leveraged the unprecedented observing infrastructure currently available in the central United States, combined with an extensive sounding array, remote sensing and in situ aircraft observations, NASA GPM ground validation remote sensors, and new ARM instrumentation purchased with American Recovery and Reinvestment Act funding. The overarching goal was to provide the most complete characterization of convective cloud systems, precipitation, and the environment that has ever been obtained, providing constraints for model cumulus parameterizations and space-based rainfall retrieval algorithms over land that had never before been available.

Instrument DescriptionThe NASA POLarimetric Radar (NPOL) is an S-band dual-polarization radar with a frequency of 2.7-2.9 GHz. A Vaisala (SIGMET) RVP-9 processor is used to provide simultaneous Receive/Transmit capability. The beam width is 0.95 degrees, and the peak power is 850 kW.
