Chlorine- and Bromine Containing Trace Gases in the Antarctic

这个项目的目的是在帕尔默站收集一套长达一年的空气样本，以调查痕量气体浓度的季节趋势。这些样本将在俄勒冈州研究生中心进行分析，以确定一些痕量成分，特别是含有氯和溴的物种。这些微量成分既来自生物来源，也来自人为来源，它们有能力改变地球气候，并以最近南极上空臭氧层耗尽的方式消耗臭氧层。这项工作被认为对更好地了解痕量组分的组成至关重要，特别是那些来自高纬度海洋的组分。提出者是该领域的领导者，设施也是独一无二的。

It is the purpose of this project to collect a year-long suite of air samples at Palmer Station to investigate the seasonal trend of the trace gas concentration. The samples will be analyzed at the Oregon Graduate Center for a number of trace components, especially chlorine and bromine containing species. These trace constituents have come from both biogenic and anthropogenic sources, and they have the capacity to alter the Earth's climate and to deplete the ozone layer in the way it has recently been depleted above Antarctica. This work is considered vital for a better understanding of the buildup of trace constituents, particularly those of high latitude marine origin. The proposers are leaders in this field, and the facilities are unique.
