Abstract
During the past decade, the Doppler Sodar (SOunding Detection And Ranging) has increasingly contributed to our understanding of the atmospheric turbulence over complex terrain through measuring wind speed and direction in a fundamentally different fashion from the traditional anemometer from the view point of volume mean.
In this paper, the field data which were obtained by two Doppler Sodars (AR-410 type, Kaijo) installed over complex terrain were compared with the results of wind tunnel experiments and numerical simulations to see how representative are the values measured by Doppler Sodars over complex terrain.
From these experiments, it is found that there are hardly any systematic errors caused by different measuring methods between mean wind speed values by anemometers and those by Doppler Sodars.
