Comparison of enhanced resolution images of Greenland from the ERS-1 and Seasat scatterometers

With the increased awareness of the role of ice sheets as a sensitive indicator of global climate change, there is greater need for synoptic interannual studies of major glacial ice masses. Only limited large scale decadal studies of the ice sheets of Antarctica and Greenland have been possible with past and present satellite systems. A recently developed resolution enhancement technique facilitates the use of scatterometer data for extended studies of glacial ice at medium scale resolution with hemispheric or even global coverage possible. The authors compare previously published results for the Seasat-A scatterometer with current ERS-1 scatterometer data for Greenland. Illustrative images and data plots are provided.<
