Dual Polarization
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.
