Abstract

Abstract

The first oceanic dynamic environment satellite—HY-2A was launched in August 16, 2011. Significant Wave Height (SWH) is one of the important parameters which can be monitored by HY-2A satellite altimeter. The SWH operational inversion algorithm of HY-2A altimeter is detail introduced in the paper, and the algorithm obtained SWH by least-square method. The SWH of HY-2A altimeter computered by the operational processing is compared to the results of Jason-2 and NDBC buoys. The result showed that the standard deviation is -0.26 cm and RMS is 0.58 cm between HY-2A and Jason-2, and the standard deviation is -0.22 cm and RMS is 0.37 m between HY-2A and NDBC buoys. The results demonstrated that the SWH inversion algorithm used in the operational processing system of HY-2A altimeter is feasible.
