利用Envisat数据探测中山站至Dome A条带区域冰盖高程变化

Elevation Change from Zhongshan Station to Dome A Using Envisat Data

  • 摘要: 在中山站至Dome A条带区域,利用2002-10~2007-09的Envisat RA2数据,对交叉点分析中的单一法、静态法与动态法进行了比较,结果表明:① 动态参考算法优于其他两种算法;② 反射能量是影响卫星测高确定冰盖高程变化的重要因素;③ 研究区域冰盖高程长期变化整体处于平衡,但其分布不均匀,恩德比地地区存在明显正增长,与ICESat一致。

     

    Abstract: Single, fixed and dynamic methods of crossover analysis are compared, and dynamic outperforms the others. The spatial distribution of elevation change from Zhongshan Station to Dome A is estimated during October 2002 to September 2007. Backscattered power is an important factor to derive elevation change. The adjusted height change over the study area is in whole balance but unevenly distributed. The positive increase is shown in Enderby Land, which agrees with ICESat.
