Jakob Steiner and team use digital elevation models and Landsat imagery in combination with high resolution Planet data to quantify surface elevation changes and flow velocities during a glacial surge of the Khurdopin Glacier. They conclude that the high frequency of Planet imagery is useful to capture peak surge velocities that are easily missed by less frequent Landsat imagery, observe surface changes that indicate potential drivers of a surge, and monitor hazards associated with a surge.
