埃波长指数能很好地反映大气气溶胶粒子的大小。与米氏法相比，拉曼法所需参数少，但精度高。介绍了用于对流层气溶胶光学特性观测的L 625拉曼-米氏双波长激光雷达，并利用L 625激光雷达的观测数据计算和分析了对流层气溶胶的波长指数。对对流层气溶胶光学特性的一些典型特征进行了观测和讨论。结果表明，L 625激光雷达测量对流层气溶胶波长指数是可靠的。
Angstrom wavelength exponents can well reflect the size of atmospheric aerosol particles. Raman method supposes less parameters but acquires higher precision when compared with Mie method. The L625 Raman-Mie dual-wavelength lidar which has been developed for obsen'ations of tropospheric aerosol optical properties is presented, then the tropospheric aerosol wavelength exponents are calculated and analyzed using data from L625 lidar. Some typical characteristics of tropospheric aerosol optical properties are observed and discussed. Results indicate that L625 lidar is reliable for the measurement of tropospheric aerosol wavelength exponents.
