摘要：
The acoustic sounder (sodar) can be used to measure the parameters of turbulence in the lower part of the atmospheric boundary layer. We suggest a new method to estimate the vertical structure of the momentum flux up to the height of several hundred meters above the surface. The method uses sodar-measured profiles of mean wind and of the variance of vertical wind component sigma(2)(w),. The field experiment have shown a good agreement of sodar-derived momentum flux values with those measured in situ. We obtained the typical profiles of momentum flux with the method.
