ICESat-2 Senses Elevation Change Over Time

NASA’s ICESat-2 satellite repeats its set of orbits every 91 days, measuring heights along these orbits in each season. In three months, the ATLAS instrument will measure this same orbit track to reveal how the elevation of these melt ponds in west central Greenland have changed since August 2.

Measuring Elevation One Photon at a Time

ICESat-2’s ATLAS instrument measures surface height by sending photons to Earth and timing their return to the instrument. The black line in this elevation profile comprises detected photons and reveals the relative elevation of the ice sheet surface, including melt pond surfaces and bases.
