This visualization explores 25 years of elevation measurements from the Airborne Topographic Mapper over the Rink glacier in Greenland. Each year is color-coded with blues representing the oldest data and red representing the newest. The camera zooms in to a view comparing data collected from many aircraft flights over the same region, showing the ice loss over several years. The camera then zooms out to see the coverage pattern for ICESat-2, which will study ice loss on a global scale.
