The University of Arizona AGRHYMET Planning Visit proposal is aimed at establishing a new research collaboration between The University of Arizona and AGRHYMET in Niger (Niamey). The funds will support the visit of a University of Arizona team, under the direction of Juan B Valdes and Aleix Serrat-Capdevila, to Niamey (Niger) for a research planning visit to AGRHYMET. A specialized institute of the Permanent Interstate Committee for Drought Control in the Sahel (CILSS) composed of nine member states, AGRHYMET is a Centre of Excellence in the science and techniques for regional agro-meteorological and hydrological monitoring, among other domains of expertise. The goal of the visit is to elaborate a joint research agenda to improve the spatio-temporal characterization of precipitation in the African Monsoon Region using both ground and satellite estimates, and to improve the use of satellite precipitation estimates in hydrologic applications and early warning systems. To achieve these goals, we will compare rain gauges and satellite precipitation measurements from different sources and different spatial scales and resolutions, across different latitudes in the African Monsoon Region (i.e. the Inter-Tropical Convergence Zone). We will also evaluate local calibrations and bias corrections of satellite measurements, and perform an analysis of the uncertainty contained in the estimates. Finally we will also compare the use of different precipitation products in lumped and distributed hydrologic models for basins in different monsoon regions.This planning visit and later communication between teams will lead to a well organized and focused scientific research agenda aimed at improving real-time precipitation estimates with important broader implications in terms of precipitation monitoring, streamflow forecasting and water resources management (allocation, reservoir operations) in poorly gauged basins across the world. For this reason, this proposal has the support of ICIWaRM-UNESCO (International Center for Integrated Water Resources Management) and the Secretariat of the Sub-Saharan G-WADI network program of UNESCO, chaired by AGRHYMET.

亚利桑那大学AGRHYMET规划访问提案旨在建立亚利桑那大学和AGRHYMET在尼日尔（尼亚美）的新研究合作。这些资金将用于资助亚利桑那大学的一个小组在Juan B Valdes和Aleix Serrat-Capdevila的指导下访问尼亚美（尼日尔），对农业气象学和水文气象学中心进行研究规划访问。AGRHYMET是由9个成员国组成的萨赫勒国家间抗旱常设委员会（萨赫勒抗旱委员会）的一个专门机构，是区域农业气象和水文监测科学和技术以及其他专门知识领域的一个英才中心。这次访问的目的是拟订一项联合研究议程，利用地面和卫星估计数改进非洲季风区降水量的时空特征，并改进卫星降水量估计数在水文应用和预警系统中的使用。为了实现这些目标，我们将比较来自不同来源、不同空间尺度和分辨率的雨量计和卫星降水测量，跨越非洲季风区（即热带辐合带）的不同纬度。我们还将评估卫星测量的本地校准和偏差校正，并对估计值中包含的不确定性进行分析。最后，我们还将比较不同的降水产品在不同季风区流域的集中和分布式水文模型中的使用。这次计划访问和随后团队之间的沟通将导致一个组织良好和重点突出的科学研究议程，旨在改善实时降水估计，在降水监测、径流预报和水资源管理方面具有重要的广泛意义（分配、水库运营）的重要性。因此，这项建议得到了教科文组织国际水资源综合管理中心和由农业水文气象学和水文气象学研究中心主持的教科文组织撒哈拉以南非洲水资源发展倡议网络方案秘书处的支持。
