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呈现出强烈的季节性变化，而且往往是强烈的异常现象，或春季破坏事件引起的臭氧消耗事件。 利用麦克默多罗斯海区域现有的自动气象站网络，将部署一些基于光度测量的臭氧测量仪，以建立麦克默多地区表层臭氧分布的多季记录。这反过来又将使罗斯海区域的季节性表面臭氧变化记录得以汇集。对影响对流层臭氧的自然背景过程与任何迁移或当地（麦克默多区域，Ant）污染成分（如氮氧化物）或自然来源的卤素之间的联系需要更好地加以解释。一名博士后助理的持续职业发展，以及参与该提案的一名本科生将是这项工作的一个重要成果。

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.
