The Coastal Zone: A Mission Target for Satellite Altimeters

Summary of the 7th Coastal Altimetry Workshop; Boulder, Colorado, 7–8 October 2013



Synthetic aperture radar (SAR) altimetry is rapidly becoming the most efficient way to measure small-scale changes in elevations of ice, land, and water surfaces as well as sea ice thickness. This new generation altimeter, first launched on board the CryoSat-2 satellite, fires 10 times more radar pulses per second than the previous generation and exploits the motion of the spacecraft to achieve a 20-fold increase in along-track resolution and twofold improvement in its accuracy.
