Changes in the location of key ice facies/zones on the Greenland ice sheet are considered key indicators of global climate change, Microwave scatterometers are effective tools for monitoring these changes. Measurements for three Ku-band scatterometers, SASS (1978), NSCAT (1996), and SeaWinds (1999-present), span a 23 years period. while the ERS scatterometer (C-band) offers a continuous 9 year dataset (1992-present). Using the SIR algorithm to produce u" images, the meiisurements made by these
