Trace Gases in Arctic Haze: Patterns and Time Variations

该项目是对北极大气中痕量气体的分析， 确定人为成分来源的目标， 被称为北极霾的大气污染事件， 并确定北极霾的性质和来源。 从在北极上空作业的NOAA WP-3飞机上采集的空气样本 1989年春季的海洋，将分析的浓度 大约30种痕量气体 其中包括含氯氟烃、溴- 含气体、轻质烃、一氧化二氮和一氧化碳 和二氧化物。 如果辅以气象测量， 在主要的现场实验中获得的支持数据， 项目是一个部分，可以识别来源地区和目标， 与以前的实地实验的类似观察相比， 将有可能评估的年际变化， 影响大气化学的人为来源 高北极

This project is an analysis of trace gases in the arctic atmosphere with the goal of defining the sources of the anthropogenic components in atmospheric pollution episodes that have become known as Arctic Haze, and to determine the nature and sources of precursors of arctic haze. Air samples, taken from a NOAA WP-3 aircraft operating over the Arctic Ocean in the Spring of 1989, will be analyzed for the concentrations of about 30 trace gases. These will include chlorofluorocarbons, bromine- containing gases, light hydrocarbons, nitrous oxide, and carbon monoxide and dioxide. When supplemented with meteorological measurements and supporting data obtained in the major field experiment of which this project is a part, source regions and tajectories can be identified, and when compared to similar observations on previous field experiments, it will be possible to assess the interannual variability in the anthropogenic sources that influence the atmospheric chemistry of the high arctic.
