Abstract :
HY-2 satellite was successfully launched on 16 August, 2011. It carried three main microwave instruments into space for operationally observing dynamic ocean environment parameters on a global scale. HY-2 satellite altimeter provides sea surface height, significant wave height, sea surface wind speed. Current status of HY-2 satellite altimeter is put forward in this study. By comparison with the other satellite data, NDBC data and other data, the accuracy of the HY-2´s data products is evaluated in this work.
