A field test program was conducted to evaluate the potential of two indirect wind sensing techniques as possible support in a warm fog dispersal system. The sensors examined were a Laser Doppler Velocimeter and an Acoustic Doppler Wind Sounder. Data from these devices were correlated with measurements taken by anemometers mounted upon a 61-m meteorological tower. The average deviation of the Laser Doppler Velocimeter was + or - 1.0 m/sec in wind speed and + or - 7 deg in azimuth. Five-minute averaging periods were taken and four to six altitudes were scanned during each run. The average deviation of the Acoustic Doppler Wind Sounder for 5-min averages was + or - 0.9 m/sec in wind speed and + or - 13 deg in azimuth. In one protracted run using 10-min averages, the deviations were + or - 0.6 m/sec in wind speed and + or - 6 deg in azimuth.
