Dual Polarization


Dual Polarization Beams Restricted Logon

In the spring of 2003 the National Weather Service Office of Science and Technology tasked the National Severe Storms Laboratory with providing data collection and analysis to support a WSR-88D dual polarization decision briefing to the NEXRAD Program Management Committee. The Joint Polarization Experiment (JPOLE) project was designed to evaluate the engineering design and data quality of the polarimetric KOUN WSR-88D radar and demonstrate the utility of polarimetric radar data and products to operational users. The NSSL JPOLE experiment demonstrated the performance improvements dual polarization provided in rainfall estimates, hydrometeor classification, and general data quality.
