Chlorine- and Bromine Containing Trace Gases in the Antarctic

这个项目的目的是收集一套长达一年的 帕尔默站的空气样本，以调查季节性趋势 痕量气体浓度。 样本将在 俄勒冈州研究生中心的一些微量成分， 尤其是含氯和溴的物质。 这些微量 成分来自生物和人类 他们有能力改变， 地球的气候和消耗臭氧层的方式 最近在南极洲上空被耗尽。 这项工作被认为是至关重要的，以更好地了解 微量成分的积累，特别是高纬度的成分 海洋起源 提案人是这一领域的领导者， 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.
