A pre-EarthScope ground velocity map for the Basin and Range Province based on InSAR

0454552美国迈阿密大学阿梅隆和蒂姆·迪克森地区的InSAR地面速度场在这个项目中，通过分析欧洲遥感卫星(ERS)获得的高空间分辨率、高精度的新的西部盆地和山脉省1992-2004年间的地表速度场。欧洲航天局提供了2000张合成孔径雷达图像，以支持这一项目。InSAR的速度场可以解释为垂直速度场，因为InSAR测量的是雷达卫星视线方向的速度，而视线方向几乎是垂直的。使用新的叠加和时间序列分析方法实现高精度测量。InSAR速度场用于探测西部盆地中地面变形增加的区域和范围，这些区域可以通过EarthScope的详细、多学科测量活动来确定目标。将这一前地镜速度场与地镜时代的速度场进行比较，将对西部盆地和山脉的瞬时变形的性质提供新的见解。

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.
