Long-term measurements of nitrogen oxides at the GEOSummit station, Greenland

在GEOSummit站对氮氧化物的长期测量：化石燃料燃烧产生的非技术抽象污染往往从附近大陆输送到北极地区，导致温室气体增加。北极气候对温室气体的影响特别敏感。气温的最初上升减少了冰盖，暴露了下方较暗的海洋，吸收了更多的辐射，导致进一步变暖。监测北极的这些污染物对于了解已经发生的变化及其对未来气候的影响非常重要。该项目将在格陵兰岛的GEO顶峰站提供氮氧化物的长期测量。人类活动和森林火灾造成的污染空气可能含有相对较高水平的氮氧化物。当这些氮氧化物被运送到北极时，可以促进臭氧的产生，臭氧是一种重要的温室气体。这些测量将提供有关输送到北极的氮氧化物浓度的重要信息，这些浓度随季节和年度变化，以及由此对北极臭氧水平的影响。该项目将为北极观测网络(AON)和北极环境变化研究(SEARCH)做出贡献。这些数据将提供给研究人员，以提高对当前运输污染对温室气体水平的影响的了解，并估计北极地区的气候变化反馈。这些数据还将被教育工作者用于课堂教学，并通过利用最先进的技术提供一个独特的机会，促进他们在大气科学领域的研究兴趣和教育增长，从而支持对应届研究生的培训。

Long-term measurements of nitrogen oxides at the GEOSummit station: Non-technical abstract Pollution from fossil fuel combustion is often transported to the Arctic region from nearby continents resulting in an increase in greenhouse gases. The Arctic climate is particularly sensitive to the effects of greenhouse gases. The initial rise in temperature reduces ice cover, exposing the darker oceans below which absorb more radiation leading to further warming. Monitoring these pollutants in the Arctic is important to understand the changes that have occurred and the impact on the future climate. This project will provide long-term measurements of nitrogen oxides at the GEOSummit Station, Greenland. Polluted air from human activities and forest fires can contain relatively high levels of nitrogen oxides. When transported to the Arctic, these nitrogen oxides can foster the production of ozone, a significant greenhouse gas. The measurements will provide important information on the concentrations of nitrogen oxides transported to the Arctic, which vary both seasonally and annually and the resulting impact on Arctic ozone levels. The project will contribute to the Arctic Observing Network (AON) and the Study of Environmental Arctic Change (SEARCH). The data will be made available to researchers for studies to improve understanding of current impacts of transported pollution on greenhouse gas levels and estimates of climate change feedbacks within the Arctic. The data will also be utilized by educators for classroom teaching and support the training of new graduate students by providing a unique opportunity to further their research interests and educational growth in the field of atmospheric sciences, using state of the art technology.
