In addition to satellite Earth observation instruments, satellite technology can also be used in other ways to help monitor and validate our understanding of ice sheet dynamics. For example, GPS data can help to accurately track movements in the ice sheet.

In this video, Professor Steffen describes how continuous GPS measurements of movements at automatic weather stations have helped us to accurately understand, model, and predict Greenland ice sheet dynamics.

He also discusses the essential role of regular hands-on measurements and observations by field scientists, even in extreme conditions, to complement and corroborate remote sensing data and models.
