InSAR surface deformation dataset for southern Onatrio, Canada

The study is to exam if surface deformation occurs in southern Ontario, Canada and if so, if it is related to changes in water storage change. The surface deformation dataset, derived from the Radarsat-2 InSAR images over five years (from Jan. 2013 to Sept. 2017), presents a surface subsidence trend from 2013 to 2017. The comparisons of the InSAR observed surface deformation and hydrological data indicate that the surface deformation in southern Ontario could be caused by water loading.

本研究旨在检验加拿大安大略省南部是否发生地表形变，若发生，则该形变是否与水体储量变化相关。本研究所用地表形变数据集源自2013年1月至2017年9月五年间的Radarsat-2合成孔径雷达干涉测量（Interferometric Synthetic Aperture Radar，简称InSAR）影像，该数据集呈现了2013至2017年的地表沉降趋势。对InSAR观测得到的地表形变与水文数据的对比分析表明，安大略省南部的地表形变或由水体荷载变化引发。
