C-band synthetic aperture radar (SAR) imagery from the European Space Agency's ERS-1 satellite reveals the basic zonation of the surface of the Greenland Ice Sheet. The zones have backscatter signatures related to the structure of the snowpack, which varies with the balance of accumulation and melt at various elevations. The boundaries of zones can be accurately located with the use of this high-resolution imagery. The images also reveal a large flow feature in northeast Greenland that is similar to ice streams in Antarctica and may play a major role in the discharge of ice from the ice sheet.
欧洲航天局ERS-1卫星的C波段合成孔径雷达（SAR）图像揭示了格陵兰冰原表面的基本分区。这些区域具有与积雪结构相关的后向散射特征，积雪结构会随着不同海拔高度的积累和融化平衡而变化。利用这种高分辨率图像可以精确确定区域边界。这些图像还揭示了格陵兰东北部一个大型流动特征，它类似于南极洲的冰流，可能在冰原的冰排放中起主要作用。
