owing to recent developments in the eld of remote sensing technology. Microwave remote sensing
is playing a major role by providing year- round data for conducting research in the remote polar
environment.
In recent years, satellite observations have provided us with much needed support in increasing
our understanding about the AIS. Different satellite- based techniques are now being utilized to
observe and monitor different aspects of AIS, such as glacier ice ow [10– 13], ice thickness change
[14, 15], mass balance [4, 11, 16, 17, 18], grounding line uctuation [19, 20], and changing gravi-
tational attraction [21, 22].
Glacier velocity is one of the crucial parameters that needs re
