Coyote UAS: A new tool to help us better
understand, initialize & evaluate...

Flight Patterns

In addition to manned aircraft, the physics evaluation observing plan would also include the use of unmanned aircraft such as Nasa's Global Hawk (when available) as well as small low altitude UAS assets such as the Coyote shown here. It should be noted that in 2014 NOAA will be obtaining several outfitted Coyote UAS as part of the recently awarded Sandy Supplemental project. Here the Coyote UAS is depicted. As noted in this graphic the Coyote is deployed using NOAA's P-3 aircraft and its associated Sonobuoy (AXBT) launch chute.

Small Unmanned Aircraft Vehicle Experiment

Part of IFEX Goal 2: Develop new measurement technologies

SUAVE objectives:

  • Improve understanding of TC near-surface energy transfer process
  • Ocean/Atmosphere T/q/M exchange processes
  • Investigate eye/eyewall T/q/M exchange processes
  • Dramatically enhance existing sparse thermodynamic coverage (esp. moisture) within the TC boundary layer
  • Provide new (continuous) TCBL observations for use in Model evaluation:
  • Compare/contrast/validate w/coincident, instantaneous TC BL observations
  • Compare UAS BL fields w/existing numerical BL structure

Potential Operational Benefits:

  1. Use UAS data to improve the accuracy of model initialization, parameterizations, physics (and ultimately) operational performance
  2. Unique -continuous- measurements of V10 in the eyewall (better Vmax?)
  3. Early detection of rapid intensity change (-> 'loitering' in the eye)

There are many advantages using the Coyote low flying UAS. However for evaluation purposes none may be as valuable as its ability to capture low level thermodynamic quantities (particular atmospheric moisture) at altitudes below typical manned P-3 flight. This flight experiment is part of IFEX's Goal 2 which is to Develop and refine measurement technologies that provide improved real-time monitoring of TC intensity, structure, and environment.
