Ladybug - Windspeed


i have a query re wind speeds.

a) Wind Boundary Profile: Wind Speeds @ various height. What is the datum i.e. 0.0, is it the sea level?

b) Outdoor Comfort Model: It considers wind speed @ 10.0 meters. However, in windy countries like NZ, discomforting winds (approx 14m/s) winds blow at ground level. Hoe do we take that into consideration in our Outdoor Comfort Model?

Kind regards,
