摘　　要：A Doppler sodar system controlled by microcomputer is described in this paper. The sodar was used to detect the vertical distribution of wind and temperature stratification in the atmospheric boundary layer. The detecting results show that at night the vertical distribution of wind is very complicated, which can appear as a structure of two or three layers. In nocturnal atmospheric boundary layer sometimes there exists very thin layer in multi-layer inversion and it can be retained for a long time.A Doppler sodar system controlled by microcomputer is described in this paper.
