南极洲的特罗尔大气站（72°01′S，2°32′E，1309 m a.s.l.）于2007年初成立并投入运营。测量方案的主要重点是沿海区和内陆冰高原之间过渡区的污染和浮质，补充了沿着南极海岸和南极高原的现有观测方案。经过一年的运作，监测方案已全面运作，正在分析一套全面的数据。就现有可比数据而言，以往数据和新数据之间的一致性令人满意。气溶胶数据和污染测量结果都表明，沿海气团全年都有间歇性的影响。中等寿命的污染物，如CO，O3和汞的背景值比相应的北极地区低50%（取决于季节），但仍然显着。臭氧总量和紫外线剂量表明，南极平流层臭氧空洞反复出现，其严重程度中等，但在2007年持续存在。目前正在对气溶胶浓度升高和汞活化的具体事件进行详细调查，并将单独发表。
The Troll Atmospheric Station in Antarctica (72°01′S, 2°32′E, 1309 m a.s.l.) was established and put into operation in early 2007. The main foci of the measurement programme are pollution and aerosols in the transition zone between the coastal zone and the inland ice plateau, complementing existing observation programmes along the Antarctic coast and on the Antarctic Plateau. After one year of operation, the monitoring programme is fully operative, and a comprehensive set of data is being analysed. As far as comparable data are available, there is satisfactory agreement between previous and new data. Both aerosol data and measurements of pollution indicate the episodic influence of coastal air masses throughout the year. Background values of medium long-lived pollutants such as CO, O3 and Hg are up to 50% lower than at corresponding Arctic sites (depending on the season), but are still significant. Total ozone and UV doses manifest the recurring Antarctic stratospheric ozone hole, which was moderately severe, but very persistent in 2007. Specific episodes of elevated aerosol concentration and mercury activation are currently under detailed investigation, and will be published separately.
