Seven-year variation in glacier surface velocity at Narsap Sermia in Southwest Greenland [PDF]

GIScience & Remote Sensing, 2023
Glacier velocity is a critical factor closely related to ice dynamics of the Greenland ice sheet (GrIS). We present variations of ice velocity using space-based synthetic aperture radar (SAR) observations from July 2013 to September 2020.
