CLEANER: Collaborative Research: Concept Development Toward a Collaborative Large-Scale Engineering Analysis Network for Environmental Research with Focus on the Chesapeake Bay

0414372提议建立一个网络基础设施环境实地基金，重点放在凤凰城及其区域环境，作为国家科学基金会清洁行动工程分析网络的一个潜在节点。这项名为MEASURES(城市和区域生态系统多尺度环境分析)的EFF将强调与空气和水的流动以及流动污染物在一系列时空尺度上的传输和扩散有关的科学、工程和社会经济问题。采用尖端传感器和通信技术的密集观测、详细的理论分析和实验室实验、高性能计算模拟、复杂的预测建模和传感器-模型融合是要采用的关键方法。数据和新的调查结果将以适当的形式迅速传播：向支持政策/决策和规划的公职人员传播，向资源管理人员传播以进行适应性管理，向公众传播引发知情讨论的信息，向研究人员传播科学发现和知识创造。在这个规划提案中，一个“概念验证”项目被提议作为措施的前提。它涉及到对多个时空尺度的气流模式的广泛监测，来自点源的污染物羽流的移动及其在亚利桑那州凤凰城周围区域的沉积。考虑到亚利桑那州东部的某些湖泊受到这种神经毒素的污染，将特别关注与区域发电厂排放有关的总汞；这似乎是一个严重的全球问题的区域对应问题，该问题主要归因于航空运输/沉积和径流。

0414372 Ball It is proposed to create a cyberinfrastructured Environmental Field Facility (EFF), focusing on the Phoenix metropolis and its regional environs as a potential node of the Engineering Analysis Network of the NSF's CLEANER initiative. This EFF, called MEASURES (Multi-scale Environmental Analysis in Urban and Regional Ecosystems), will emphasize scientific, engineering and socio-economic issues related to the flow of air and water as well as transport and dispersion of flow-borne contaminants over a range of spatio-temporal scales. Intense observations that employ cutting-edge sensor and communications technologies, detailed theoretical analyses and laboratory experiments, high-performance computational simulations, sophisticated predictive modeling and sensor-model fusion are the key approaches to be employed. The data and new findings will be disseminated rapidly in suitable formats: to public officials in support of the policy/decision making and planning, to resource managers for adaptive management, to the general public for triggering an informed discourse, and to the researchers for scientific discovery and knowledge creation. In this planning proposal, a"proof-of-concept."project is proposed as an antecedent to MEASURES. It involves extensive monitoring of air flow patterns of multiple space-time scales, movement of contaminant plumes from point sources and deposition thereof in the regional domain circa urban Phoenix, Arizona. Particular attention will be paid to total Mercury (Hg) associated with regional power plant emissions, considering that certain lakes in eastern Arizona are contaminated by this neurotoxin; this appears to be a regional counterpart of a serious global problem that is largely attributed to aerial transport/deposition and runoff.
