Workshop on the proposed Network of Mountain Observatories for Composition of the Atmosphere

关于拟议的大气成分山地观测站网络（MOCA）的研讨会将把大气科学家聚集在一起，制定一项长期计划，以协调美国大陆多个高海拔地点的研究工作。高海拔地区的大气测量很少，山区研究观测站的连续采样提供了关于区域背景大气成分长期变化的关键信息。以及季节性和日间过程以及极端事件（例如野火、放射性核素释放、火山灰、沙尘暴和平流层侵入）。拟议的网络跨越美国不同的气候带和生态系统，包括四个国际公认的大气研究观测站，这些观测站已经运行了几十年，定位良好，可以观测从西部到美国大陆的大气流和从东部到美国大陆的大气流。研讨会的具体目标是：(1)进一步发展和完善每个拟议科学主题（活性微量气体、温室气体、气溶胶和辐射、云和降水）内的研究目标；(2)确定满足这些研究目标所需的关键测量；(3)确定策略，利用不同科学主题内的测量来解决额外的研究目标或更好地解决现有的研究目标；(4)确定将特别受益于跨站点的一套通用测量的研究目标；(5)制定指标，优先考虑研究目标；(6)评估每个站点作为全球站纳入全球大气监视网的测量基础设施和数据管理需求；(7)鼓励批判性讨论如何最好地在多个站点实施和管理如此广泛的研究目标，包括数据管理计划；(8)为每个研究目标制定时间表，在每个站点进行初始仪器集成；(9)确定与其他机构和地方/区域利益相关者进行有意义和富有成效的合作的机会；（10）确定在每个站点维持长期、校准良好的测量的策略。讲习班的结论将通过讲习班摘要出版物加以传播。该奖项反映了美国国家科学基金会的法定使命，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。

The Workshop on the proposed Network of Mountain Observatories for Composition of the Atmosphere (MOCA) will bring together atmospheric scientists to develop a long-term plan for coordinating research efforts at multiple high-elevation sites within the continental U.S. Atmospheric measurements at high altitudes are sparse, and continuous sampling at mountain research observatories provides access to critical information about long-term changes in regional background atmospheric composition, as well as seasonal and diurnal processes and extreme episodes (e.g. wildfires, radionuclide releases, volcanic ash, dust storms, and stratospheric intrusions). The proposed network spans across different climatic zones and ecosystems in the U.S. and includes four internationally recognized atmospheric research observatories, which have been in operation for decades and are well-positioned to observe both atmospheric flow to the continental U.S. from the west and atmospheric flow to the east. Specific goals of the workshop will be to: (1) further develop and refine the research objectives within each of the proposed science themes (reactive trace gases, greenhouse gases, aerosols and radiation, and clouds and precipitation); (2) identify critical measurements needed to meet these research objectives; (3) identify strategies to leverage measurements within different science themes to address additional research objectives or to better address existing research objectives; (4) identify research objectives that would especially benefit from a common set of measurements across sites; (5) develop metrics to prioritize research objectives; (6) evaluate the measurement infrastructure and data management needs for each site to be incorporated into the Global Atmospheric Watch (GAW) network as a global station; (7) encourage critical discussion about how best to implement and manage such a broad range of research objectives across multiple sites, including a data management plan; (8) develop a timeline for each research objective, following initial instrument integration at each site; (9) identify opportunities for meaningful and productive collaboration with other agencies and local/regional stakeholders; and (10) identify strategies for sustaining long-term, well-calibrated measurements at each site. Conclusions from the workshop will be disseminated through a workshop summary publication.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.
