- Аннотация: The frequency response of different types of sonic anemometers due to spatialaveraging of turbulent fluctuations along the sonic path is investigated byapplying modeling procedures and by sonic measurements. The data wereobtained simultaneously at up to 4 heights over extreme smooth andhomogeneous terrain during stationary situations, varying fromslightly stable to unstable. It is shown thatcorrections for the variance of the vertical wind component areneeded for measurements close to the ground. A correction procedure, based ona response function for the vertical wind and on parameters derived frompower spectra, is applied to the measurements. At a height of about onemetre, the variance of the vertical wind component is typicallyunderestimated by about 10%. The error decreases with increasing height. It isalso shown that in the height range down to one metre other turbulencequantities, as for example the variances of the horizontal wind components andthe turbulent fluxes of momentum and sensible heat, are not markedly affectedby the sonic spatial response. Experimental data support these findings.
