NPOL

NPOL (NASA Polarimetric precipitation radar) is operating in S-Band, research grade, transportable dual-polarimetric radar first developed in 2001 by a research team from NASA's Wallops Flight Facility. It is used to make accurate volumetric measurements of precipitation including rainfall rate, particle size distributions, water contents and precipitation type. The radar uses a magnetron-transmitter with a solid-state pulse modulator. The antenna has a prime-focus parabolic reflector which is 8.5 m in diameter. The NPOL underwent a complete antenna system upgrade in 2010 and is housed on five intermodal containers.
