OU-PRIME (Polarimetric Radar for Innovations in Meteorology and Engineering) is an advanced Doppler weather radar. It was completed in January 2009 after a ten-month construction period and commissioned on April 4, 2009.〔 〕 It is operated by the Advanced Radar Research Center (ARRC) at the University of Oklahoma (OU). The radar was manufactured by Enterprise Electronics Corporation to provide OU students and faculty a platform for research and education in the field of radar meteorology. This C-band polarimetric radar has the highest resolution of any C-band, polarimetric, research, weather radar in the United States and possibly the world.〔〔〔 〕 OU-PRIME was struck by lightning on 19 March 2012 around 9:20am local time. Since then, the radar has not been operated due to damage.〔 == System characteristics == OU-PRIME, aka OU', is located on the Research Campus of the University of Oklahoma within walking distance of the National Weather Center building. Through a unique design, OU-PRIME can provide real-time time-series data providing opportunities for rapid developments in radar signal processing algorithms. Because of its C-band wavelength and 1 MW transmit power, OU-PRIME is extremely sensitive to clouds with approximately 10 dB more sensitivity over the NEXRAD system (S-band).
