Recently there has been much discussion about the relationship between traditional 10-minute average NFDRS wind observations and forecasts at 20-feet, 2-minute average 10-meter winds from NWS ASOS sites and mid-flame (1.8 meter) masts from the new Fire RAWS. This paper reports on an initial investigation based on 3 RM Young ultrasonic anemometers located at 10-meters, 6-meters (20-feet), and 1.8 meters (6-feet) above the ground on the same mast. Sampling at a rate of 10 Hz, 1-second averaged data were collected at a number of locations in western Montana during the summer of 2003. Characteristics of the wind speed probability distributions and correlations between the sampling heights and averaging times are presented.
