One of the instruments that flew aboard one of two unmanned Global Hawk aircraft during NASA's HS3 mission was the Hurricane Imaging Radiometer known as HIRAD. HIRAD identified an area of heavy rains and and likely strong winds in Hurricane Ingrid by measuring surface wind speeds and rain rates using its rectangular antenna to track activity on the ocean's surface.
