U.S.-Azores (Portugal) Collaborative Study of CO, O3, and Black Carbon at PICO-NARE

美国和葡萄牙合作评估北美和欧洲大陆排放对北大西洋地区对流层组成的影响，这一为期两年的奖项由密歇根理工大学的Richard Honrath和葡萄牙亚速尔大学的Paulo Fialho获得。皮科国际大气化学观测站将对臭氧、一氧化碳、黑碳和气象参数进行为期两年的测量，以验证从北美平流到北大西洋中部的羽流中存在显著臭氧形成的假设。美国研究人员将在北大西洋地区偏远野外地点进行大气化学测量方面的专业知识带到这次合作中，他们将提供测量站基础设施。此外，葡萄牙还将提供亚速尔群岛地区大气和陆地条件方面的专门知识；葡萄牙将提供黑碳测量。这项研究的结果预计将有助于理解人类活动对地球辐射预算的影响，并有助于改进对当前和未来对气候影响的估计。

0110397HonrathThis two-year award for US-Portugal collaboration on assessing the impacts of continental emissions from North America and Europe upon tropospheric composition in the North Atlantic region involves Richard Honrath of Michigan Technological University and Paulo Fialho at the University of the Azores, Portugal. Measurements of ozone, carbon monoxide, black carbon, and meteorological parameters will be made at the Pico International Atmospheric Chemistry Observatory for a two-year period to test the hypothesis that significant formation of ozone occurs in plumes from North America advected toward the central North Atlantic. The US researchers bring to this collaboration expertise in atmospheric chemistry measurements at remote field sites in the North Atlantic region and they will provide the measurement station infrastructure. This is complemented by Portuguese expertise in atmospheric and land conditions in the Azores region; the Portuguese will provide black carbon measurements. The results of this research are expected to contribute to an understanding of anthropogenic impacts on the earth's radiation budget, and aid the development of improved estimates of current and future impacts on climate.
