Because of their light weight, slower air speed and limited endurance, most small Unmanned Aircraft Systems (UAS) are much more susceptible to variations in wind speed/direction and turbulence occurring on much finer scales than that impacting commercial aircraft. Sudden changes in wind speed and direction can render small UAS unrecoverable if the resulting head winds exceed performance characteristics. At the same time, UAS trying to maintain level/smooth flight in areas of more intense turbulence can run out of power more quickly than anticipated.  In an attempt to mitigate these operational constraints, NCAR has developed a fine-scale realtime modeling capability that can be used to provide guidance on fine-scale variability of winds,  as well as the location, intensity and duration of turbulence hazards. This new capability will be demonstrated during ISARRA (International Society for Atmospheric Research using Remotely-piloted Aircraft) Flight Week in July 2018. Wind and turbulence data collected during coordinated flight missions will be used to evaluate and improve the model.
