Integrating Microwave Link Data For Analysis of Precipitation in Complex Terrain: Theoretical Aspects and Hydrometeorological Applications (IMAP)

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。对其时空分布的详细了解是可持续水管理的关键先决条件，范围从管理有限的水供应和农业、工业或家庭的水分配，到管理洪水风险和民事保护。我们将通过融合不同的降水信息来获得高分辨率的雨量场。来自商业手机链路数据的微波导出线综合降水估计将与传统的量规和雷达观测相结合，并进一步同化到高分辨率大气模式中。将首次获得巴勒斯坦移动电话供应商(Jawwal)提供的微波链路数据，并将其与以色列的数据合并。此外，来自德国商业链路的大量微波衰减数据将首次通过移动电话公司(爱立信)直接提供。方法和方法将在以色列、巴勒斯坦和德国更大的地区进行测试和评估。特别关注选定的三个目标流域：以色列的Wadi Darga、巴勒斯坦的Wadi Faria和德国的Ammer山脉。这三个目标区的特点都是地形复杂、多山，降雨量在空间和时间上变化很大，降水-径流响应时间很快。改进洪水预报方法的必要性是所有三个目标区域的中心问题，而改进的水资源可获得性估计当然在干旱的以色列和巴勒斯坦目标区域具有更大的重要性。我们决定使用一个共同和联合的水文气象模式系统：将为三个目标区域使用和进一步发展WRF-HYDRO耦合的大气和水文模式。这将有助于更好地了解和量化整个区域水循环，并有可能改进洪水预报。

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.
