The high-altitude airborne radar group at NASA Goddard Space Flight Center covers all aspects of high-altitude airborne Doppler radars from hardware development, deployment, processing, and performing science studies with the data. They have participated in NASA field campaigns for over 20 years with focus on hurricanes and convection, TRMM, GPM, and CloudSat validation, and more recently snow storms. Several aircraft used for these studies including the NASA ER-2, WB-57, and Global Hawk.
