Measurements of atmospheric ozone at altitudes from 5 to 50 km using the lidar (DIAL) differential absorption technique are described. A XeCl excimer laser with a repetition rate of up to 50 Hz and a wavelength of 308 nm was used for the measurements. The reference line was produced by the stimulated Raman effect in a hydrogen gas cell, leading to a wavelength of 353 nm. The time-resolved measurement of the backscattered light allows one to evaluate the ozone concentration as a function of the altitude. Exceptionally good agreement between the lidar data and those measured with chemical balloonsondes was obtained. A narrow-band laser and a receiving system, including a set of three Fabry-Perot filters, also allow daytime measurements. Thus investigations in polar regions are possible even in summer periods. Measurements performed in arctic and equatorial regions with the lidar system installed on board the research vessel Polarstern are reported.
描述了使用激光雷达（DIAL）差分吸收技术在5至50千米高度测量大气臭氧的方法。测量使用了重复频率高达50赫兹、波长为308纳米的XeCl准分子激光器。参考线由氢气室中的受激拉曼效应产生，波长为353纳米。对后向散射光的时间分辨测量使人们能够评估臭氧浓度随高度的变化。激光雷达数据与化学探空气球测量的数据之间获得了非常好的一致性。一个窄带激光器和一个包括一组三个法布里 - 珀罗滤波器的接收系统也允许进行白天测量。因此，即使在夏季，也可以在极地地区进行调查。报告了使用安装在研究船“极地星号”上的激光雷达系统在北极和赤道地区进行的测量。
