0548376ZebkerThis grant supports upgrade of the capacity, security and accessibility of the Western North America Interferometric Synthetic Aperture Radar (WInSAR) imagery archive through acquisition of three Pentium 4 based mass store systems, each with Redundant Arrays of Internal Disks (RAID), and an additional dual 64 bit CPU compute server for WinSAR data pre-processing. WInSAR is an organization of 32 member institutions created to aid InSAR research by acquiring requested spaceborne SAR data and distributing them to the science community so that data and analysis techniques may be shared among researchers. The requested equipment would increase the capacity of the WInSAR online distribution server, which currently archives approximately 7500 scenes of ERS-1/2 and Envisat data for on-line access by academic and government institutions, to over 20,000 scenes. The upgraded WInSAR archive would support a range of geophysical and tectonic research by faculty and students at WInSAR consortium institutions. The traditional scientific focus of WinSAR investigators has been study of crustal deformation of the western part of North America and ramifications for understanding the geodynamics of the upper mantle, earthquake physics, volcanic, subsurface fluid and orogenic processes who rely on the InSAR technique for unique spatially continuous observation of deformation over broad areas (to 100's of km). The upgraded archive and on-line processing capabilities would immediately benefit and complement the scientific objectives of the MREFC funded EARTHSCOPE Plate Boundary Observatory (PBO). WInSAR data continue to support undergraduate and graduate student research at nearly all the consortium member institutions and the expanded archive would ultimately support acquisition of Japanese ALOS L-band SAR data at locations that extend beyond the traditional Western North America focus. Much of the research facilitated by archive holdings has implications for hazard mitigation, both earthquake and volcanic, as well as studies of anthropogenically influenced subsurface fluid movements. ***

0548376 Zebker该拨款支持通过购买三个基于Pentium 4的海量存储系统来升级北美西部干涉合成孔径雷达（WInSAR）图像存档的容量、安全性和可访问性，每个系统都具有内部磁盘冗余阵列（RAID），以及用于WinSAR数据预处理的额外双64位CPU计算服务器。 W干涉合成孔径雷达是一个由32个成员机构组成的组织，其目的是通过获取所需的星载合成孔径雷达数据并将其分发给科学界，以便研究人员可以共享数据和分析技术，从而协助干涉合成孔径雷达研究。所要求的设备将增加WInSAR联机分发服务器的能力，该服务器目前将ERS-1/2号卫星和环境卫星数据的大约7，500个场景存档，供学术机构和政府机构联机访问，目前将增加到20，000多个场景。 升级后的WInSAR档案将支持WInSAR联盟机构的教师和学生进行一系列地球物理和构造研究。 WinSAR研究人员的传统科学重点是研究北美西部的地壳变形及其对了解上地幔地球动力学、地震物理学、火山、地下流体和造山过程的影响，他们依赖于干涉合成孔径雷达技术来进行独特的空间连续观测大范围的变形区域（至数百公里）。 升级后的档案和在线处理能力将立即有利于和补充由海洋环境与渔业委员会资助的地球观测仪板块边界观测站的科学目标。 WInSAR数据继续支持几乎所有联合体成员机构的本科生和研究生研究，扩大的档案最终将支持在传统的北美西部重点以外的地点获取日本ALOS L波段合成孔径雷达数据。 许多研究促进了档案持有的影响，减灾，地震和火山，以及研究受地质影响的地下流体运动。***
