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.

0315533 Wahr描述：该奖项是为了支持科罗拉多博尔德市科罗拉多大学物理系John Wahr博士和埃及El-Sadat市Menoufia大学沙漠环境研究所Mohammed Shaltout博士之间的合作项目。 主要目标与美国航天局和德国航天局于2002年3月发射的为期5年的GRACE重力卫星任务有关。 这两个目标都涉及GRACE监测埃及地下水和地表水大规模平均变化的能力。这些目标是：（1）验证GRACE数据，以确保它们不断满足精度规格;（2）使用GRACE对埃及大规模水变化的测量，以监测长期含水层枯竭以及土壤和底土层中可用于农业目的的水量变化等情况。 作为实现这些目标的努力的一部分，PI将继续获取全国各地气压计记录的压力和温度数据，包括东南部沙漠周围地区。 适用范围：该项目是在国家科学基金会国际科学和工程处赠款下启动的一个项目的继续，是将时变卫星重力观测纳入水文科学的总体努力的一部分。 这些观测结果构成了一种新的、创新的水文数据类型，在增进对全球水循环的了解方面大有希望。 该项目将使埃及的科学家熟悉这种新数据类型的分析，埃及是一个水资源问题相当重要的国家。 该项目得到了美国-埃及联合基金方案的支持，该方案向两国的科学家和工程师提供赠款，以开展这些合作活动。
