    Tracking mountainous glaciers using TanDEM-X

    Ice melting from mountain glaciers is one of the largest contributors to sea-level rise outside the large ice sheets of Antarctica and Greenland. New research leveraging the vast data from the TanDEM-X mission, has successfully mapped glacial elevation change over multiple mountainous regions of the world.
