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

关于拟议的大气成分山区观测站网络（莫卡）的讲习班将汇集大气科学家，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。在山区研究观测站进行连续采样，区域背景大气成分的长期变化以及季节性和日变化过程和极端事件（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，能够很好地观测从西部流向美国大陆的大气流和流向东部的大气流。讲习班的具体目标是：（1）进一步制定和完善每个拟议科学主题的研究目标（2）确定实现这些研究目标所需的关键测量;（3）确定战略，以利用不同科学主题内的测量来实现其他研究目标或更好地实现现有研究目标;（4）确定将特别受益于一套跨站点的共同测量的研究目标;（5）制定衡量标准，以确定研究目标的优先次序;（6）评价将作为全球台站纳入全球大气观测网的每个站点的测量基础设施和数据管理需要;（7）鼓励就如何最好地在多个地点实施和管理如此广泛的研究目标进行批判性讨论，包括数据管理计划;（8）在每个地点初步整合仪器后，为每个研究目标制定时间轴;（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）确定在每个地点维持长期、校准良好的测量的战略。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。

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.
