Acquisition of a Multi-Processor Computer System for a SAR Interferometry Processing Facility

这笔赠款为购买一台多处理器计算机和工作站，以在加州大学洛杉矶分校地球和空间科学部内建立用于固体地球地球物理研究的干涉合成孔径雷达(InSAR)处理设施的费用提供部分支持。这位名叫Gilles Peltzer的PI是加州大学洛杉矶分校ESS系的新成员，此前他曾在喷气推进实验室担任了10年的研究科学家。除了G.Peltzer的团队，包括博士后学者和研究生在内，该系统将被更多的教职员工使用，包括但不限于教授。计算机服务器将允许处理和分析大量InSAR数据集，用于研究旨在了解地震发生后的地下过程、这些事件后的应力松弛、火山喷发以及更多地表效应，包括地壳流体提取和重新注入产生的地表变形。使用InSAR进行的观测(提供采样的空间连续性)理想地补充了使用永久性GPS阵列进行的观测(时间连续性)。快速分析和解释这两组地球物理数据的能力将立即对加州大学洛杉矶分校地球和空间科学系的几位科学家进行的大地测量和地震学研究有用。

0091845PeltzerThis grant provides partial support of the costs of acquiring a multi-processor computer and workstations to set up an interferometric synthetic aperture radar (InSAR) processing facility for solid Earth geophysical research within UCLA's Earth and Space Sciences Department. The PI, Gilles Peltzer, is a recent addition to the ESS department faculty at UCLA, after having spent 10 years as a research scientist at the Jet Propulsion Laboratory. In addition to G. Peltzer's group including post-doctoral scholars and graduate students, the system will be used by a larger group of faculty including, but not limited to, Profs. J. Vidale, D. Jackson and collaborating scholars engaged in processing and analysis of massive data sets and CPU-intensive physical modeling.The computer server will allow processing and analyses of large sets of InSAR data for research aimed at understanding sub-surface processes involved in the generation of earthquakes, the relaxation of the stress following these events, volcanic eruptions, and more surficial effects including the surface deformation produced by crustal fluid extraction and reinjection. The observations made possible using InSAR (providing spatial continuity of sampling) ideally complement those made with permanent GPS arrays (temporal continuity). The ability to rapidly analyze and interpret both sets of geophysical data will be immediately useful for geodetic and seismological research conducted by several scientists within the Earth and Space Science department of UCLA.***
