本文利用安徽光机所的多波长紫外差分吸收激光雷达[1]的探测结果，在平流层背景气溶胶情况下，比较单波长(308 nm)距离差分方法和双波长(308－355nm)差分方法受气溶胶和温度影响的结果。比较结果表明：单波长距离差分方法受温度变化和气溶胶的不均匀影响较大，双波长差分方法受影响较小，两种方法的处理结果有明显差异。30天的平均结果表明：在19 km以下，单波长结果与双波长结果相差较大；在19～35 km高度区间，单波长结果与双波长结果的相对误差小于12％。
In this paper, datum obtained by multiwavelength UV-DIAL lidar at Anhui Institute of Optics and Fine Mechanics are used to compare the effects of temperature and aerosol on singlewavelength (308 nm) and two-wavelength(308－355 nm) DIAL with backgr ound stratospheric aerosol. Results of two methods show that the effects are larger for single-wavelength DIAL but less for two-wavelength DIAL. Calculated results of two methods are different distinctly. A mean value of 30 days show difference of ozone results measured by single-wavelength and twowavelength is comparably large below 19 km altitude. Relative errors of single-wavelength to two-wavelength are less than 12% from the height of 19 km to 35 km.
