The Tropospheric Ozone Lidar Network (TOLNet) is a unique network of lidar systems that measure high-resolution atmospheric profiles of ozone. The accurate characterization of these lidars is necessary to determine the uniformity of cross-instrument calibration. From July to August 2014, three lidars, the TROPospheric OZone (TROPOZ) lidar, the Tunable Optical Profiler for Aerosol and oZone (TOPAZ) lidar, and the Langley Mobile Ozone Lidar (LMOL), of TOLNet participated in the "Deriving Information on Surface conditions from Column and Vertically Resolved Observations Relevant to Air Quality" (DISCOVER-AQ)mission and the "Front Range Air Pollution and Photochemistry Éxperiment" (FRAPPÉ)to measure ozone variations from the boundary layer to the top of the troposphere. This study presents the analysis of the intercomparison between the TROPOZ, TOPAZ, and LMOL lidars, along with comparisons between the lidars and other ozone instruments including ozonesondes and a P-3B airborne chemiluminescence sensor. In terms of the range-resolving capability, the TOLNet lidars measured vertical ozone structures with an accuracy generally better than ±15% within the troposphere. Larger differences occur at some individual altitudes in both the near-field and far-field range of the lidar systems, largely as expected. In terms of column average, the TOLNet lidars measured ozone with an accuracy better than ±5% for both the intercomparison between the lidars and between the lidars and other instruments. These results indicate very good measurement accuracy for these three TOLNet lidars, making them suitable for use in air quality, satellite validation, and ozone modeling efforts.
对流层臭氧激光雷达网络（TOLNet）是一个独特的激光雷达系统网络，用于测量高分辨率的臭氧大气廓线。准确表征这些激光雷达对于确定跨仪器校准的一致性至关重要。2014年7月至8月，TOLNet的三台激光雷达，即对流层臭氧（TROPOZ）激光雷达、气溶胶和臭氧可调谐光学廓线仪（TOPAZ）激光雷达以及兰利移动臭氧激光雷达（LMOL），参与了“从与空气质量相关的柱面和垂直分辨率观测中获取地表状况信息”（DISCOVER-AQ）任务和“前缘空气污染与光化学实验”（FRAPPÉ），以测量从边界层到对流层顶的臭氧变化。本研究展示了对TROPOZ、TOPAZ和LMOL激光雷达之间相互比较的分析，以及这些激光雷达与其他臭氧仪器（包括臭氧探空仪和P - 3B机载化学发光传感器）之间的比较。在距离分辨能力方面，TOLNet激光雷达在对流层内测量垂直臭氧结构的精度通常优于±15%。在激光雷达系统的近场和远场范围内的某些个别高度处出现了较大差异，这在很大程度上是预期之中的。在柱平均方面，TOLNet激光雷达在激光雷达之间以及激光雷达与其他仪器之间的相互比较中，测量臭氧的精度均优于±5%。这些结果表明这三台TOLNet激光雷达具有非常好的测量精度，使其适用于空气质量、卫星验证和臭氧建模工作。
