The Airborne Third Generation Precipitation Radar (APR-3) is an airborne Doppler dual-polarization radar. It measures Doppler velocity and radar reflectivity at three frequencies: 13.4 GHz, 35.6 GHz, and 94 GHz. These measurements are used to determine the vertical structures of clouds and precipitation characteristics. APR-3 has a horizontal resolution of 700-800 meters at an altitude of 10 km and a vertical resolution of 60 meters. It was developed by NASA's Jet Propulsion Laboratory (JPL) and replaced the APR-2.
