0315533WahrDescription: This award is to support a collaborative project between Dr. John Wahr, Department of Physics, University of Colorado, Boulder, Colorado and Dr. Mosalam Shaltout, Desert Environment Research Institute, Menoufia University, El-Sadat City, Egypt. The primary objectives are related to the 5-year GRACE gravity satellitemission, launched in March 2002 by NASA and DLR (the German Space Agency). Bothobjectives involve the ability of GRACE to monitor changes in large-scale averages of ground-and surface-water in Egypt. These objectives are:(1) to validate the GRACE data to make sure they are continually meeting accuracy specifications; and (2) to use the GRACE measurements of large-scale water variability in Egypt to monitor such things as long-term aquifer depletion, and changes in the amount of water in the soil and sub-soil layers available for agricultural purposes. As part of the effort to achieve these goals, the PIs will continue the acquisition of pressure and temperature data as recorded at barometers throughout the country, including in the region surrounding the southeastern desert. Scope: This project is the continuation of a project initiated under a grant from NSF, Office of International Science and Engineering, and is part of an overall effort towards integrating time-variable satellite gravity observations into the hydrological sciences. These observations constitute a new and innovative data type for hydrology, with considerable promise for improved understanding of the global water cycle. This project will allow scientists from Egypt, a country where water resource issues are of considerable importance, to familiarize them with the analysis of this new data type. 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.

0315533WAHRDESCRIPTION：该奖项是为了支持科罗拉多州科罗拉多大学，科罗拉多州科罗拉多大学物理学系的John Wahr博士与埃及埃尔萨达特市Menoufia University的沙漠环境研究所的Mosalam Shaltout博士之间的合作项目。 主要目标与NASA和DLR（德国航天局）于2002年3月发起的5年Grace Grace Gracity SatelliteSsion有关。 Bothobjectives涉及宽限期监测埃及地面和地表水平均值的变化的能力。这些目标是：（1）验证宽限数据以确保它们不断符合准确性规格； （2）使用埃及的大规模水变异性的宽限期测量来监测诸如长期含水层耗竭之类的东西，以及用于农业目的的土壤和次土层中的水量变化。 作为实现这些目标的努力的一部分，PI将继续收购全国范围内的高压仪，包括东南沙漠周围地区的压力和温度数据。 范围：该项目是国际科学与工程办公室赠款启动的项目的延续，是将时间变化的卫星重力观测结果整合到水文科学中的整体努力的一部分。 这些观察结果构成了一种用于水文学的新的创新数据类型，并有很大的希望，可以提高对全球水周期的了解。 该项目将允许来自埃及的科学家，在这个国家，水资源问题非常重要，可以使他们熟悉这种新数据类型的分析。 该项目得到了美国埃及联合基金计划的支持，该计划为两国的科学家和工程师提供了这些合作活动的赠款。
