We analyze the long‐range transport to high latitudes of a smoke particle filament originating from the extratropics plume after the Australian wildfires colloquially known as “Black Saturday” on 7 February and report the first Antarctic stratospheric lidar characterization of such aerosols. Using a high‐resolution transport/microphysical model, we show that the monitoring cloud/aerosol lidar instrument operating at the French Antarctic station Dumont d'Urville (DDU, 66°S to 140°E) recorded a signature of those aerosols. The 532 nm scattering ratio of this filament is comparable to typical moderate stratospheric volcanic plume, with values between 1.4 and 1.6 on the first and third days of March above DDU station at around the 14 and 16 km altitude, respectively. A dedicated model is described and its ability to track down fine optical signatures is validated against Antarctic lidar elastic aerosol and DIAL ozone measurements. Using 1 month of tropical Cloud‐Aerosol Lidar with Orthogonal Polarization (CALIOP) data to support a relatively simple microphysical scheme, we report modeled aerosol presence above DDU station after advection of the aerosol size distribution. In situ measurements also report associated positive ozone anomaly. This case study provides evidence that biomass burning events injecting significant amounts of material up to stratospheric altitudes can be transported toward high latitudes. We highlight a potential imprint of smoke particles on the Antarctic atmosphere over larger time scales. Any underestimation of the global impact of such deep particle transport will lead to uncertainties in modeling the associated chemical or radiative effects, especially in polar regions, where specific microphysical and chemical processes take place.

2009年澳大利亚野生动植物的长距离运输检测南极气溶胶

我们分析了澳大利亚野火在2009年2月7^日被通称为“黑色星期六”后，由热带风羽产生的烟雾颗粒细丝向高纬度的远距离迁移，并报告了这种气溶胶的第一个南极平流层激光雷达特征。使用高分辨率传输/微物理模型，我们显示了在法国南极气象站Dumont d'Urville（DDU-66°S-140°E）上运行的监测云/气溶胶激光雷达仪器记录了这些气溶胶的特征。此细丝的532nm的散射率比得上典型中等平流层火山羽份，用在1 1.4和1.6之间的值^ST和3^次 3月的天数分别在DDU站上方约14 km和16 km。
