Scientists have now delivered the first measurements of Greenland Ice Sheet thickness change using CryoSat-2 and ICESat-2 – the ESA and NASA ice satellite missions. Both satellites carry altimeters as their primary sensor, but they make use of different technologies to collect their measurements. CryoSat-2 carries a radar system to determine the Earth’s surface height, while ICESat-2 … Continue reading Measuring Greenland’s Melting Ice Sheet
