Abstract

Abstract

Since the satellite launched,the cross-calibration,validation and quality assessment for HY-2A satellite radar altimeter product have been ongoing. In this paper,we finish the verification work that HY-2A satellite altimeter 44th cycle IGDR product data was compared with Jason-2 IGDR through global distribution,two-dimensional histogram and the daily average methods. While the main environmental parameters and geophysical product data quality analysis showed that data quality are stable. In addition,the analysis of the SSH differences at crossovers between HY-2A ascending and descending tracks,the SSH differences at HY-2A and Jason-2 and sea Level Anomaly (SLA) along track have been done to evaluate performance of HY-2A satellite altimeter observation system,the results showed that sea surface height accuracy is about 7.48 cm,close to Jason-2. It can meet the needs of marine applications and scientific research.
