FIRST ASSESSMENT OF HY-2A ALTIMETER DATA OVER ANTARCTICA AND GREENLAND USING CROSSOVER ANALYSIS
The radar altimeter onboard China's HY-2A satellite was launched in August 2011 and it can provide the surface elevation measurements from 80.6 degrees N to 80.6 S. In this letter, the precision of the HY-2A elevation measurements over the Antarctica ice sheet (AIS) and the Greenland ice sheet...
