项目摘要

The objective of IMAP is to develop and apply new methods for the quantification of precipitation in regions of complex terrain. The detailed knowledge of its spatio-temporal distribution is the crucial prerequisite for sustainable water management, ranging from managing limited water availability and water distribution in agriculture, industry or households to managing flooding risks and civil protection. We will derive high resolution rainfall fields by merging different precipitation information. Microwave derived line integrated precipitation estimates originating from commercial cellphone link data will be combined with traditional gauge and radar derived observations and additionally assimilated into a high resolution atmospheric model. For the first time microwave link data from a Palestine cell phone provider (Jawwal) will be acquired and combined with data from Israel. Also for the first time, a large number of microwave attenuation data from commercial links in Germany will be made available directly via a cellphone company (Ericsson). Methods and approaches will be tested and evaluated for larger regions in Israel, Palestine and Germany. A special focus is set on three selected target catchments: the Wadi Darga in Israel, the Wadi Faria in Palestine and the Ammer mountains in Germany. All three target regions are characterized by complex, mountainous terrain, high rainfall variability in space and time, and fast precipitation-runoff response times. Necessity for improved flood forecasting methods is a central issue for all three target regions, while improved water availability estimates of course have a higher importance in the dry Israeli and Palestine target regions. We have decided to use one common and joint hydro-meteorological model system: the coupled atmospheric and hydrological model WRF-Hydro will be used and further developed for the three target regions. This will allow for an improved understanding and quantification of the full regional water cycle and has the potential to improve flood forecasting.

IMAP的目标是开发和应用新的方法来量化复杂地形地区的降水量。详细了解水的时空分布情况是可持续水管理的关键先决条件，包括管理农业、工业或家庭的有限水供应和水分配，以及管理洪水风险和平民保护。我们将通过合并不同的降水信息来获得高分辨率的降水场。从商用手机链路数据中得出的微波线综合降水估计值将与传统的测量仪和雷达观测结果相结合，并进一步同化到高分辨率大气模型中。将首次从巴勒斯坦移动电话供应商（Jawwal）获得微波链路数据，并将其与以色列的数据合并。此外，德国商业链路的大量微波衰减数据将首次直接通过一家手机公司（爱立信）提供。将在以色列、巴勒斯坦和德国的较大区域测试和评价各种方法和途径。一个特别的重点是三个选定的目标集水区：以色列的Wadi Darga，巴勒斯坦的Wadi Faria和德国的Ammer山脉。所有这三个目标区域的特点是复杂的山区地形，降雨量在空间和时间上变化很大，降水径流反应时间快。改进洪水预报方法的必要性是所有三个目标区域的一个中心问题，而改进水供应估计数在以色列和巴勒斯坦干旱目标区域当然更重要。我们已决定使用一个共同的联合水文气象模型系统：将使用并进一步发展三个目标区域的大气和水文耦合模型WRF-Hydro。这将有助于更好地了解和量化整个区域的水循环，并有可能改善洪水预报。
