项目摘要
Climate warming in the Arctic has been 2-3 greater than in any other environment on Earth. There has been an increase in tundra wildfire occurrences in coastal Greenland in recent years, setting a new all-time record in summer 2017. A growing body of literature suggests that this increase in arctic wildfires is largely due to drier summer conditions from increasing temperatures, increasing length of the snow-cover free season, and increased lightning, all of which are linked to the arctic warming. This project focuses on the study of emissions from arctic tundra wildfires. Chemical tracers of wildfires, including carbon monoxide, methane, and a series of volatile organic compounds will be monitored in the atmosphere at the Greenland Environmental Observatory at Summit (GEOSummit), which, while considered one of the most pristine and remote locations in the Northern Hemisphere, has previously been shown to receive fire plumes from coastal Greenland and other arctic regions further away. Observations will be applied in modeling research to assess the impacts of the increasing frequency and geographical extent of fires on the arctic environment and lower latitudes.This project will deliver continuous high time resolution data for wildfire emission and climate forcing atmospheric constituents at GEOSummit. All data will be submitted to the Arctic Data Center for worldwide dissemination. Data analyses and modeling will improve assessments of fire emissions and their environmental and climate impacts. Results and interpretations will be presented in university class room teaching, seminars, at conferences, and in peer-reviewed journal publications. Observations will make a pivotal contribution to the World Meteorological Organization (WMO) Global Atmospheric Watch (GAW) program. This research will also contribute to the following programs: Study of Environmental Arctic Change (SEARCH), Cryosphere and Atmospheric Chemistry (CATCH), Pollution in the Arctic: Climate, Environment and Societies (PACES), and the international Year of Polar Prediction (YOPP). It addresses the need for ?long-term atmospheric measurements?, as stipulated in the Report on the Future of Atmospheric Chemistry Research to NSF.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
北极的气候变暖比地球上任何其他环境都要高2-3倍。近年来,格陵兰沿海的苔原野火发生率有所增加,在2017年夏季创下了新的历史纪录。越来越多的文献表明,北极野火的增加在很大程度上是由于气温升高导致的夏季干燥,无积雪季节的长度增加以及闪电增加,所有这些都与北极变暖有关。该项目的重点是研究北极苔原野火的排放。野火的化学示踪剂,包括一氧化碳,甲烷和一系列挥发性有机化合物将在格陵兰环境观测站(GEOSummit)的大气中进行监测,该观测站被认为是北方半球最原始和偏远的地点之一,此前已被证明可以接收来自格陵兰沿海和其他北极地区的火羽。 观测结果将用于模拟研究,以评估火灾频率和地理范围的增加对北极环境和低纬度地区的影响,该项目将在GEOSummit上提供野火排放和气候强迫大气成分的连续高时间分辨率数据。 所有数据将提交给北极数据中心,供全球传播。 数据分析和建模将改善对火灾排放及其环境和气候影响的评估。 研究结果和解释将在大学课堂教学、研讨会、会议和同行评议的期刊出版物上发表。 观测将对世界气象组织(WMO)的全球大气观测(GAW)计划做出关键贡献。这项研究还将有助于以下项目:北极环境变化研究(STAR),冰冻圈和大气化学(CATCH),北极污染:气候,环境和社会(PACES)和国际极地预测年(YOPP)。 它解决了需要?长期的大气测量该奖项反映了NSF的法定使命,并通过使用基金会的知识价值和更广泛的影响审查标准进行评估,被认为值得支持。
