This collaborative research project is being undertaken by Dr. Emad Habib, University of Louisiana at Lafayette, and Dr. Mohamed Abdel-Motaleb, Egyptian Ministry of Water Resources and Irrigation. Egypt is expected to face increasing water needs due to rapidly growing population, economic growth and urbanization. To prepare for such challenges, the Nile Forecasting Center (NFC) in the Egyptian Ministry of Water Resources and Irrigation operates a suite of hydrologic simulation models and analysis tools that support current and future strategies for sustainable water resources management and planning. NFC relies on satellite infrared (IR) imagery to estimate rainfall information over the Nile Basin, which is the main input to NFC hydrologic models. Due to the inherent limitations of IR-based rainfall estimates, the proposed project aims to improve on the current NFC rainfall estimation algorithms. Two types of enhancements are proposed for improving the current NFC algorithm: (1) adding more infrared channels that have become recently available to NFC from the Spinning Enhanced Visible Infrared Imager (SEVIRI) onboard a Meteosat Second Generation (MSG) satellite, and (2) integrating other valuable satellite data from passive microwave sensors which are not currently used by the NFC algorithm (the Special Sensor Microwave/Imager (SSM/I) and the Advanced Microwave Sounding Unit (AMSU)). These enhancements will be implemented within a self-calibrating satellite-rainfall estimation algorithm to be configured and tested over the Nile basin. The project activities will be conducted as collaboration between researchers at NFC and the University of Louisiana (UL) at Lafayette. Satellite data and algorithm support will be contributed by the NOAA's National Environmental Satellite Data and Information Service (NESDIS). The new rainfall estimates developed in the project will be statistically validated using surface gauge measurements and will be evaluated in comparison to infrared-only estimates that are currently produced at NFC.The research will inform the scientific community regarding the accuracy of satellite rainfall products in understudied regions, and it will also provide feedback on the added benefit of incorporating additional satellite sensors which are only available in Europe and Africa. The outcome of the project has significant implications for water resource management in Egypt and has the potential to validate algorithms for use in the US. Additionally, the project will present opportunities for US undergraduates and graduate students to obtain international research experience in Egypt.The project is funded under the US-Egypt Joint Fund Program, which provides grants to scientists and engineers in both countries to undertake cooperative research.

该合作研究项目由路易斯安那大学拉斐特分校的 Emad Habib 博士和埃及水资源和灌溉部的 Mohamed Abdel-Motaleb 博士承担。由于人口快速增长、经济增长和城市化，埃及预计将面临日益增长的用水需求。为了应对这些挑战，埃及水资源和灌溉部的尼罗河预报中心（NFC）运行了一套水文模拟模型和分析工具，支持当前和未来的可持续水资源管理和规划战略。 NFC 依靠卫星红外 (IR) 图像来估计尼罗河流域的降雨信息，这是 NFC 水文模型的主要输入。由于基于红外的降雨估算的固有局限性，该项目旨在改进当前的 NFC 降雨估算算法。提出了两种类型的增强功能来改进当前的 NFC 算法：(1) 添加更多的红外通道，这些通道最近已从 Meteosat 第二代 (MSG) 卫星上的旋转增强型可见红外成像仪 (SEVIRI) 可供 NFC 使用，以及 (2) ）集成来自 NFC 算法当前未使用的无源微波传感器的其他有价值的卫星数据（特殊传感器微波/成像仪 (SSM/I) 和高级微波探测单元 (AMSU)）。这些增强功能将在自校准卫星降雨估计算法中实施，并在尼罗河流域进行配置和测试。该项目活动将由 NFC 和路易斯安那大学 (UL) 拉斐特分校的研究人员合作开展。卫星数据和算法支持将由 NOAA 的国家环境卫星数据和信息服务 (NESDIS) 提供。该项目中开发的新降雨量估算将使用表面测量仪测量进行统计验证，并将与 NFC 目前生成的仅红外估算进行比较进行评估。该研究将向科学界通报正在研究的卫星降雨产品的准确性。它还将提供有关纳入仅在欧洲和非洲提供的额外卫星传感器的额外好处的反馈。 该项目的成果对埃及的水资源管理具有重大影响，并有可能验证在美国使用的算法。 此外，该项目还将为美国本科生和研究生提供在埃及获得国际研究经验的机会。该项目由美国-埃及联合基金计划资助，该计划为两国科学家和工程师进行合作研究提供资助。
