IWRAP 3D Winds in Hurricane Larry (20210907) Derived from the Ku-band Radars

On 7 September 2021, a NOAA WP-3D flew a mission through Hurricane Larry with the Imaging Wind and Rain Airborne Profiler (IWRAP) mounted on the aircraft. Horizontal wind vectors and atmospheric wind speeds were retrieved from the Ku-band radar measurements, and are presented with equivalent reflectivity estimates from IWRAP and other measurements and retrievals from collocated instruments (e.g., flight-level wind sensors and the Stepped Frequency Microwave Radiometer [SFMR]). The radar was configured to sample at two incidence angles: 31 degrees and 51 degrees. The former utilized a short pulse waveform and the latter a longer linear frequency modulated chirp waveform.
