Doppler radar is a valuable meteorological tool used to analyze precipitation, air motion (including wind shear), and storm dynamics. CP-2 was one of the first Doppler radars installed at the National Center for Atmospheric Research. It featured two receiving dishes that allow horizontal and vertical signals to be received at the same time. This allows scientists to distinguish--and infer the shapes of--hailstones, snow, rain, cloud droplets, ice crystals, and graupel. Part of CP-2 was reused in S-Pol, a portable Doppler radar used in field projects across North America and beyond.
