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