| 摘 要： | 基于Mie散射大气激光雷达,应用Klett算法对回波信号进行了反演,得到大气消光系数和后向散射系数。然后,通过对大气后向散射系数曲线进行拟合得到大气边界层混合层高度以及卷夹层厚度等特征参数。对比雷达实测数据与探空气球所测数据,证明二者存在较好相关性。基于实测数据讨论了四川盆地大气边界层特性对气候的影响。

| Abstract: | By using Mie scattering laser lidar,aerosol extinction coefficient and backscatter coefficient were inverted by using Lidar returns and Klett inversion method.Then the characteristic parameters of mixed layer height and entrainment zone width of the atmospheric boundary layer were obtained by fitting inverted backscatter coefficient curve.It has a good correlation between Lidar data and the sounding-balloon data.The influence of atmospheric boundary layer on the climate of Sichuan basin was discussed based on the detected data. |
