Colin will look into how to do damping of the direction and speed readimg.
- Wind Speed
- Wind Gust
- The international standard for anemometer height above the ground is 10 meters (33 feet) with no obstructions.
- CWOP requires wind direction reports in degrees from true north.
Sampling Standards
- Mean Wind Speed and Direction: 2-minute mean of speed and direction sampled before the observation valid time sampled from high-resoluation data (minimum: 5 second instrument polling).
- Gust: Maximum 'instantaneous' wind value observed in the 10 minutes before the observation time.
CWOP
- Averaging Wind Speed and Direction
- Wind Energy Resource Atlas of the United States
- Vector vs. Scalar Averaging of Wind Data
[Farmland] lists wind direction, speed, and gust.
