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

该拨款提供了购买多处理器计算机和工作站的部分费用支持，以建立干涉合成孔径雷达（InSAR）处理设施，用于加州大学洛杉矶分校地球和空间科学系的固体地球物理研究。首席研究员吉尔斯·佩尔策（Gilles Peltzer）是加州大学洛杉矶分校ESS系的新成员，此前他在喷气推进实验室（Jet Propulsion Laboratory）做了10年的研究科学家。除了包括博士后学者和研究生在内的G. Peltzer小组外，该系统还将被包括但不限于教授在内的更大的教师小组使用。J. Vidale， D. Jackson和合作学者从事处理和分析大量数据集和cpu密集型物理建模。计算机服务器将允许处理和分析大型InSAR数据集，用于研究地震产生的地下过程、地震事件后应力的松弛、火山爆发以及更多的地表影响，包括地壳流体提取和再注入产生的地表变形。使用InSAR（提供采样的空间连续性）所获得的观测结果理想地补充了永久性GPS阵列（时间连续性）所获得的观测结果。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学和地震学研究有用

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.***
