The Haiyang-2C (H2C) mission has been launched in September 2020 by the Chinese Agency NSOAS (National Satellite Ocean Application Service). H2C is the third unit of the Haiyang-2 altimetry Program which also features HY2B (launched in October 2018) and HY2D (launched in May 2021) as well as the upcoming units E to H in the future. These satellites are dedicated to monitor the dynamic ocean environment and they bring a significant contribution to the sampling capability of the CEOS Ocean Surface Topography Virtual Constellation.



In order to assimilate H2C data into Sea Level Anomaly (SLA) Level-2P/3/4 [1][2][3][4] funded by CNES (Centre National d’Etudes Spatiales) and Wind and Waves (W&W) products L2P/L3/L4 [4] supported by CNES, and CMEMS (Copernicus Marine Environment Monitoring Service) funding, we performed a global HY2C data assessment. We obtained excellent data quality results that are shown here. We will also discuss about performance and contribution of H2C to DUACS (Data Unification and Altimeter Combination System) products into future assimilation.
