US-Egypt Cooperative Research: An Investigation of Natural and Anthropogenic Factors Leading to Elevated Particulate Matter and Ozone Levels in Egypt

9904792Hanna 描述：该奖项旨在支持由北卡罗来纳州罗利市 MCNC-北卡罗来纳超级计算中心环境研究中心 Adel Hanna 博士领导的美国团队和埃及开罗国家核安全与辐射控制中心辐射与环境监测网络 Abou Bakr Ramadan 博士领导的埃及团队的合作项目。 他们计划研究埃及城市地区的空气污染。 该研究将汇编和分析气溶胶（颗粒物、各种微量物质）的现场数据，并将其用于一组根据当地条件调整的可用数值/统计方案。他们计划利用气象数据来研究一天中不同地点和不同时间的停滞高压系统和混合层深度，并利用3D区域化学迁移模型和监管模型来进一步了解导致大气中颗粒物和臭氧水平升高的物理过程。范围：该项目可能有助于更好地了解导致埃及污染物负荷和迁移的特殊区域条件，特别是在开罗和亚历山大周围的城市走廊。 该地区人口密度非常集中；干燥的环境，降水清除机制减少，光化学生产过程丰富。现有数据及其在分析中的使用可能会产生更好的理解和知识，并影响有关由于人为活动而造成的污染物负荷的国家政策。 汉纳博士在大气建模工作方面拥有丰富的经验，之前曾与埃及联合首席研究员成功合作，并联合发表了论文。 合作者可以很好地获取所需的现场数据以及来自美国研究界的数值方案。 两国的博士后科学家将合作开展研究，并在国际科学活动中获得经验。 该提案符合 INT 支持共同感兴趣领域的合作研究的目标。 该项目得到了美国-埃及联合基金计划的支持，该计划向两国的科学家和工程师提供赠款以开展这些合作活动。

9904792HannaDescription: This award is to support a collaborative project by a US team headed by Dr. Adel Hanna, Environmental Research, MCNC-North Carolina Supercomputing Center, Raleigh, North Carolina and an Egyptian team headed by Dr. Abou Bakr Ramadan, Radiation and Environmental Monitoring Network, National Center for Nuclear Safety and Radiation Control, Cairo, Egypt. They plan to study the air pollution in urban locations of Egypt. The study would compile and analyze in-situ data on aerosols (particulate matter, various trace species) and use them in a set of available numerical/statistical schemes, tuned to local conditions. They plan to use meteorological data to study stagnant high pressure systems and the mixed-layer depth at various locations and times of day, and using 3-D regional chemical transport models and regulatory models for further understanding of the physical processes leading to elevated particulate matter and ozone levels in the atmosphere.Scope: This project may lead to a better understanding of the special regional conditions that contribute to pollutant loading and transport in Egypt, especially in the urban corridor around Cairo and Alexandria. This region has a very concentrated population density; a dry environment with reduced precipitation scavenging mechanisms, and abundant photochemical production processes. The available data and its use in the analyses may yield better understanding and knowledge and affect national policy concerning pollutant loading due to anthropogenic activity is too ambitious. Dr. Hanna has had extensive experience in atmospheric modeling work, and has worked successfully with the Egyptian co-PI before, with resulting joint publication. The collaborators are well placed to access the needed in-situ data as well as numerical schemes from US research community. Postdoctoral scientists from both countries will collaborate on the research, and will gain experience in international scientific activities. This proposal meets the INT objective of supporting collaborative research in areas of mutual interest. This project is being supported under the US-Egypt Joint Fund Program, which provides grants to scientists and engineers in both countries to carry out these cooperative activities.
