Facility Support of the WInSAR Archive for Crustal Dynamics Research

这笔赠款支持一项为期三年的努力，以：1)开发多卫星合成孔径雷达(SAR)数据排序、分发和存档系统；2)从欧洲、加拿大和日本航天局购买全球和北美新的合成孔径雷达场景；以及3)支持开发用于合成孔径雷达干涉测量(InSAR)的开源社区软件。美国仍然没有星载合成孔径雷达传感器，美国科学家在获取全球合成孔径雷达图像以支持地壳形变研究方面在很大程度上受制于外国供应商的“摆布”。InSAR提供了一种在大空间范围(100秒到1000公里)上观察地壳形变的独特视角，从而补充了GPS观测。事实证明，这项技术对于提高对火山、地震和人类活动(由于水资源和油气资源的开采)引起的地壳变形的认识具有重要价值。将合成孔径雷达现场数据档案放在联安办事处设施是具有成本效益的，而且可以借用联安办事处设施现有的数据管理人员和硬件支持。合成孔径雷达数据档案将确保美国科学家有机会利用星载合成孔径雷达图像进行一系列与全球社会相关的研究。

0733437MeertensThis grant supports a three year effort to: 1) develop a multi-satellite synthetic aperture radar (SAR) data ordering, distribution and archiving system; 2) purchase new SAR scenes globally and over North America from the European, Canadian and Japanese Space Agencies; and 3) support development of open-source community software for SAR interferometry (InSAR). The U.S. still does not have a spaceborne SAR sensor and U.S. scientists are largely at the "mercy" of foreign providers for access to global SAR imagery in support of research on crustal deformation. InSAR offers a unique look at crustal deformation over large spatial extents (100s to 1000 km) and thus complements GPS observations. The technique has proven value for advancing understanding of volcanic, seismic and anthropogenic related (due to water and hydrocarbon resource extraction) crustal deformation. Locating a SAR scene data archive at the UNAVCO Facility is cost effective and borrows on existing data management personnel and hardware support of the UNAVCO Facility. The SAR data archive will ensure that U.S. scientists are afforded the opportunity to utilize spaceborne SAR images for a range of studies of societal relevance across the globe.
