0454552AmelungAn InSAR ground velocity field for the Western Basin and Range Falk Amelung and Tim Dixon, University of Miami In this project SAR data acquired by the European Remote Sensing satellites (ERS) is analyzed to derive a new, high spatial resolution, high accuracy, surface velocity field of the Western Basin and Range Province during the 1992-2004 time period. The European Space Agency provides 2000 SAR images in support of this project. The InSAR velocity field can be interpreted as the vertical velocity field because InSAR measures velocities in direction of the line-of-sight of the radar satellite which is nearly vertical. High precision measurements are achieved using new stacking and time series analysis methods. The InSAR velocity field serves to detect areas of increased ground deformation in the Western Basin and Range that can be targeted using detailed, multi-disciplinary measurements campaigns by EarthScope. Comparison of this pre-Earthscope velocity field with the velocity field of the Earthscope era will provide new insights into the nature of transient deformation in the Western Basin and Range.

0454552 AmelungAn干涉合成孔径雷达西部盆地和山脉的地面速度场Falk Amelung和Tim狄克逊，迈阿密大学在该项目中，分析了欧洲遥感卫星（ERS）获取的SAR数据，以获得1992-2004年期间西部盆地和山脉省的新的、高空间分辨率、高精度的地面速度场。欧洲航天局为支持这一项目提供了2000幅合成孔径雷达图像。干涉合成孔径雷达速度场可以解释为垂直速度场，因为干涉合成孔径雷达测量的是雷达卫星视线方向上的速度，该方向几乎是垂直的。使用新的叠加和时间序列分析方法实现了高精度测量。干涉合成孔径雷达速度场用于探测西部盆地和山脉中地面变形增加的区域，这些区域可以通过EarthScope的详细、多学科测量活动进行定位。将此前地球镜速度场与地球镜时代的速度场进行比较，将为了解西部盆地和山脉瞬态变形的性质提供新的见解。
