Chlorine- and Bromine Containing Trace Gases in the Antarctic

本项目的目的是在帕尔默站收集一年的空气样本，以调查微量气体浓度的季节性趋势。这些样品将在俄勒冈研究生中心进行一些微量成分的分析，特别是含氯和溴的物种。这些微量成分既有生物来源，也有人为来源，它们有能力改变地球的气候，并像最近在南极洲上空消耗臭氧层那样消耗臭氧层。这项工作被认为对更好地理解微量成分的积累，特别是那些高纬度海洋成分的积累至关重要。提议者是这个领域的领导者，设施是独一无二的。

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.
