Two independent systems for determining wind speed and turbulence levels
are being used in an on-shore diffusion study on Long Island near Brookhaven
National Laboratory. Results obtained from the two instrument systems are
compared to illustrate the differences in the measured values of the vector wind,
mean wind speed, variance, turbulence level and energy spectra. Details of the
physical characteristics and relative advantages of a commercial Vector Vane and
a three-dimensional hot-film sensor are also presented. Measurements of the mean
wind speed and the turbulence level compared well. The Vector Vane
underestimated spectral densities for frequencies above 1 hertz. (auth)
