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.

9904792 HannaDescription：该奖项旨在支持一个由阿德尔Hanna博士领导的美国团队和一个由Abou Bakr Ramadan博士领导的埃及团队的合作项目，前者是MCNC-北卡罗莱纳超级计算中心（位于北卡罗来纳州州罗利市）环境研究团队，后者是埃及国家核安全与辐射控制中心辐射与环境监测网络团队。 他们计划研究埃及城市地区的空气污染。 这项研究将汇编和分析关于气溶胶（颗粒物质、各种痕量物质）的现场数据，并将其用于一套适合当地条件的现有数值/统计方案。他们计划利用气象数据研究停滞高压系统和一天中不同地点和时间的混合层深度，并利用三维区域化学传输模型和监管模型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：这一项目可能会导致更好地了解特殊的区域条件，有助于污染物的负荷和运输在埃及，特别是在开罗和亚历山大周围的城市走廊。 这一地区人口密度非常集中，环境干燥，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，并影响到关于人类活动造成的污染物负荷的国家政策。 Hanna博士在大气建模工作方面拥有丰富的经验，并曾与埃及合作伙伴成功合作，并共同发表了成果。 合作者能够很好地访问所需的现场数据以及来自美国研究界的数值方案。 来自两国的博士后科学家将合作进行研究，并将获得国际科学活动的经验。 该提案符合INT的目标，即支持在共同感兴趣的领域进行合作研究。 该项目得到了美国-埃及联合基金方案的支持，该方案向两国的科学家和工程师提供赠款，以开展这些合作活动。
