Support for a U.S. InSAR Community Workshop

我们请求资金支持一个社区研讨会，以指导美国建立美国干涉合成孔径雷达（干涉合成孔径雷达）使命的努力。 干涉合成孔径雷达是一种新型的天基雷达观测技术，它能够以数百万像素（每个像素的分辨率约为10-30米）测量地震和其他来源引起的地面位移，位移精度可达几毫米。 干涉合成孔径雷达图像在以下方面也具有重要价值：监测火山爆发;天气预报，因为雷达反射对土壤湿度变化很敏感;冰和冰川研究;以及各种地表变化和环境应用，包括估计风速和风向以及探测浮油。拟议的研讨会将于2004年10月20日至22日在加州的奥克斯纳德举行。 我们预计将从NASA获得研讨会支持的资金。 还将向美国地质勘探局申请资金。 南加州地震中心将为研讨会提供行政支持。

We request funds to support a community workshop to guide US efforts in establishing a US Interferometric Synthetic Aperture Radar (InSAR) mission. InSAR is a new type of space-based radar observation that allows ground displacements from earthquakes and other sources to be measured over many millions of pixels (each representing a resolution of about 10-30 meters) to a displacement accuracy of several millimeters. InSAR images also have significant value in monitoring volcanic eruptions; in weather forecasting, inasmuch as the radar reflections are sensitive to soil moisture variations; in ice and glacier studies; and in a variety of surface change and environmental applications, including estimates of wind velocity and direction, and detection of oil slicks. The proposed workshop will take place October 20-22, 2004 in Oxnard, California. We anticipate receiving funds from NASA for workshop support. Funds will also be requested from the USGS. The Southern California Earthquake Center will provide administrative support for the workshop.
