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

[0110397] Honrath这项为期两年的美国-葡萄牙合作项目旨在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，参与者包括密歇根理工大学的Richard Honrath和葡萄牙亚速尔群岛大学的Paulo Fialho。Pico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，以验证一个假设，即臭氧的重要形成发生在从北美向北大西洋中部平流的羽流中。美国研究人员为这次合作带来了北大西洋地区偏远地区大气化学测量方面的专业知识，他们将提供测量站的基础设施。葡萄牙在亚速尔地区大气和土地条件方面的专门知识也对这一工作加以补充；葡萄牙人将提供黑碳的测量。预计这项研究的结果将有助于了解人类活动对地球辐射收支的影响，并有助于改进对当前和未来气候影响的估计。

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.
