Abstract

The HY-2A (launched on 2011/8/16) is the first microwave marine remote sensing satellite from HY-2 satellite series developed by China. It includes a dual-frequency altimeter in Ku and C-bands. In this paper, (1) significant wave height (SWH) data from HY-2A altimeter are corrected by using collocated NDBC (U.S. National Data Buoy Centre) buoy data and are compared with Jason-1/2 data; (2) data fusion of SWH from the combination of HY-2A altimeter and other satellite altimeters (Jason-1/2 and Envisat) is given and the results are compared one another; (3) the merged SWH data from HY-2A, Jason-1/2 and Envisat are used to analyze the characteristics of SWH in China Seas and adjacent waters. Comparisons show that the results are good and HY-2A altimetry data work well with other satellite altimetry data.
