| Abstract: | The mean ENVISAT-DEM of 3 years over Antarctic ice sheet is derived from ENVISAT altimeter data applied relocation and geophysical correction.The mean height difference between ENVISAT-DEM and RAMP-DEM is about 18m,it means that their accuracies are close to each other. Moreover,the height changes of several profiles over Antarctic ice sheet between 2003 and 2006 are also analyzed,the results show that the height changes are in a range of-0.31-0.17 m. |
| Keywords: | satellite altimetry DEM Antarctic ice sheet height change ENVISAT |
