Welcome to HAR

Over the past two decades, the high-altitude airborne radar group at NASA Goddard Space Flight Center has developed the 9.6 GHz ER-2 Doppler Radar (EDOP) and the 94 GHz Cloud Radar system (CRS) for flying on NASA's ER-2 aircraft at about 20 km above the ground. Both radars have been involved in a number of field campaigns and provide vertical profiles of cloud and precipitation measurements for atmospheric research. Recent radar developments include the Hight-altitude Imaging Wind and Rain Airborne Profiler (HIWRAP), and  the ER-2 X-band Radar (EXRAD) , which is the next generation of EDOP with scanning capability.
