对臭氧的垂直观测对于理解边界层中的各种大气化学过程，特别是在冬季，起着至关重要的作用。在这项研究中，我们试图利用六轴飞行器(UAV)平台测量2018年冬季长三角地区中国地区边界层臭氧的垂直廓线。安装在保温箱中的商用便携式臭氧监测仪安装在无人机平台上，进行垂直臭氧测量。结果表明，无人机平台能够有效地捕捉冬季边界层臭氧的垂直变化。在实地活动期间，由于光化学产生较弱，地表臭氧处于相对较低的水平。白天，臭氧在边界层内混合良好。夜间，在500米以下的臭氧廓线中，常出现均匀的垂直分布型和层状分布型。利用后向轨迹和风廓线研究了臭氧的水平和垂直输送。臭氧的分层分布模式与当代臭氧的强烈平流输送密切相关，并伴随着高空风的增强。此外，强风切变增强了臭氧从自由对流层向边界层的向下输送，导致边界层臭氧的垂直分布均匀，夜间地面臭氧水平升高。这一研究结果可以为了解冬季边界层臭氧的空间变化和演变规律以及在大气化学模式中构建合适的边界层方案提供参考。
Vertical observations of ozone play vital roles in understanding various atmospheric chemical processes in the boundary layer, particularly in winter. In this study, we attempted to measure vertical profiles of boundary layer ozone in the winter of 2018 over the Yangtze River Delta region of China, using a hexacopter unmanned aerial vehicle (UAV) platform. A commercial portable ozone monitor mounted in a thermal insulation box was attached to the UAV platform to conduct vertical ozone measurements. The results showed that the UAV platform could effectively capture the vertical variations of boundary layer ozone in wintertime. During the field campaign, surface ozone was in relatively low levels due to weak photochemical production. In the daytime, the ozone was well mixed within the boundary layer. At nighttime, uniform vertical distribution patterns and stratified distribution patterns were frequently obtained in ozone profiles below 500 m. Backward trajectories and wind profiles were used to investigate the horizontal and vertical transport of ozone. The stratified distribution patterns of ozone were closely associated with strong contemporary advection transport of ozone that was accompanied by enhanced winds aloft. Besides, strong wind shear enhanced the downward transport of ozone from the free troposphere into the boundary layer, leading to uniform vertical distribution patterns of boundary layer ozone and the elevated nocturnal surface ozone levels. The results of this study could provide insights into the understanding of the spatial variations and evolution patterns of boundary layer ozone in wintertime and constructing suitable boundary layer schemes in atmospheric chemical models.
