Unique Observations in Hurricane Maria (2017) using the Coyote Uncrewed Aircraft System (UAS)
Abstract
Scientists from the National Oceanic and Atmospheric Administration (NOAA) collected valuable and highly unique data from six Coyote Uncrewed Aircraft Systems (UAS) deployed into Hurricane Maria on 22-24 September 2017. Using NOAA's crewed P-3 reconnaissance aircraft as a deployment vehicle, low-level observations of wind speed, wind direction, atmospheric pressure, temperature, moisture and sea surface temperature were measured and transmitted by the UAS. In all cases, high-definition observations collected by the Coyote were transmitted to NOAA's National Hurricane Center and made available to forecasters in near-real time. A brief synopsis of the data collected will be given. Highlights include: 1) the highest (to our knowledge) UAS-measured wind speed in a hurricane (64 m/s at 340 m above sea level); 2) record endurance for a Coyote UAS mission in a hurricane (42 minutes); and 3) high-frequency (>2 Hz) measurements in the hurricane boundary layer, which allow for calculations of turbulence intensity. Plans for data analysis and future UAS deployments in hurricanes will also be discussed.
