为了研究大气中臭氧的空间和时间演变，激光雷达系统已被证明是足够的，但仍然很复杂。我们在本文中定义了用于白天和夜间操作的对流层和平流层下层地面和机载臭氧测量的 UVDIAL 系统的主要特征。讨论了使用瑞利/米氏信号或拉曼氮信号的多波长激光雷达系统，作为有效纠正由于对流层下部气溶胶和其他干扰气体（即 SO(2)）造成的系统偏差的臭氧测量的方法。对两种类型的激光器（固态和准分子）进行了比较，因为这两种激光器都适合长期现场操作和机载使用。
To study the ozone spatial and temporal evolution in the atmosphere, lidar systems have proved to be adequate but have remained complex. We define in this paper the main characteristics of a UVDIAL system for ground based and airborne ozone measurements in the troposphere and the lower stratosphere both for daytime and nighttime operation. A multiwavelength lidar system using either Rayleigh/Mie signals or the Raman nitrogen signal, is discussed as a way to efficiently correct the ozone measurements from the systematic bias due to aerosol and other interference gases (i.e. SO(2)) in the lower troposphere. Two types of lasers (solid state and excimer) are compared, as both lasers are suitable for long term field operation and airborne use.
