Greenland Ice Sheet Surface Properties and Ice Dynamics from ERS-1 SAR Imagery
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...
