Overview

The NASA Polarimetric Radar (NPOL), developed by a research team from Wallops Flight Facility, is a fully transportable and self-contained S-band research radar. It has an ultra-modern flat panel hexagonal antenna 18 feet (5.5 meters) in diameter. The radar requires no special site preparation and can be set up on a generally flat area anywhere in the world. The system can operate continuously, 24 hours a day, 7 days a week, measuring both rainfall rates and amounts. The polarimetric data can be used to deduce the physical characteristics of hydrometeors within the radar beam.
