Collaborative Research: Augmenting the Ross Island-area automatic weather station network to develop a tropospheric ozone climatology

极地对流层臭氧浓度表现出强烈的季节变化，往往与春季破坏事件引起的强烈异常或臭氧消耗事件一样。利用麦克默多罗斯海地区现有的自动气象站网络，将部署若干基于光度法的臭氧计，以便建立麦克默多地区地表臭氧分布的多季节记录。这反过来又将使罗斯海地区季节性地表臭氧变化的记录得以汇编。影响对流层臭氧的自然本底过程与任何输送的或当地的（麦克默多地区，Ant）污染成分（如氮氧化物）或天然来源的卤素之间的联系将得到更好的解释。一名博士后助理的持续职业发展，以及一名参与提案的本科生，将是这项工作的额外成果。

Polar tropospheric ozone concentrations exhibit strong seasonal variations and often just as strong anomalies, or ozone depletion events arising from spring destruction episodes. Using the existing Automatic Weather Stations network in the McMurdo Ross Sea region, a number of photometric based ozone meters will be deployed, in order to establish a multi-season record of surface level ozone distributions in the McMurdo area. This in turn will allow a record of seasonal surface ozone variability in the Ross Sea region to be assembled. A link between natural background processes influencing tropospheric ozone and any transported or local (McMurdo region, Ant) pollution components (such as NOx) or naturally sourced halogens is to be better explained. The continued career development of a post-doctoral associate, and also an undergraduate student involved in the proposal will be an aditional outcome of this work.
