Infrared Measurements of Atmospheric Chemistry in Antarctica

这一行动将逐步停止麦克默多站用于测量各种大气成分的傅里叶变换红外光谱仪和南极站用于测量氮化合物的发射光谱仪的运行和维护。多年来建立的数据库包括氯氟烃、一氧化氮和一氧化氮、硝酸氯、氯化氢和其他在化学破坏平流层臭氧中活跃的微量元素的浓度。这些信息的实用性已经下降，因为季节性臭氧破坏的化学性质现在已经很清楚了，对大气成分的跟踪和监测是由美国国家海洋和大气管理局气候监测和诊断实验室及其在南极站的观测站进行的。该项目由美国国家科学基金会极地项目办公室和大气科学部联合支持。这些资金将用于分析南极站硝酸分布的现有数据

9814624MurcrayThis action phases out the operation and maintenance of a Fourier-transform infrared spectrometer for various atmospheric constituents at McMurdo Station, and an emission spectrometer for nitrogen compound measurements at South Pole Station. The database developed over the years includes concentrations of chlorofluorocarbons, nitrous and nitric oxides, chlorine nitrate, hydrogen chloride, and other trace elements active in the chemical destruction of stratospheric ozone. The utility of the information has decreased because the chemistry of the seasonal ozone destruction is now known quite well, and the tracking and monitoring of atmospheric constituents is being done by the NOAA Climate Monitoring and Diagnostic Laboratory with its observatory at South Pole Station. This project is jointly supported by the NSF's Office of Polar Programs and Division of Atmospheric Sciences. The funds will be used to analyze existing data on the nitric acid distribution over South Pole Station.***
