Abstract: Glacier surface elevation changes on Ányêmaqên Mountains(2000–2013) and a digital elevation model (DEM) were obtained by performing differential interferometry on bistatic satellite data TanDEM-X/TerraSAR-X and Shuttle Radar Topographical Mission digital elevation model (SRTM dem). The pixel size of the TanDEM dem is 10 m in horizontal direction, with a relative error of less than 2 m. The pixel size of the of the elevation change dataset is30 m in horizontal direction, with a relative error of 3.7 m. Unreliable regions in the radar images, which resulted from shadows and layovers, have been removed. The dataset can be a baseline for glacier elevation and volume change studies, and glacier water resources appraisal.
