HY-2A is the first altimetry and radiometry satellite of the China National Space Administration (CNSA), it was successfully launched on 15th of August 2011. The National Satellite Ocean Application Service (NSOAS) is responsible for the ground segment and for distributing collected data and HY-2A L2 products. The French contribution performed by the Centre National d’Etudes Spatiales (CNES) on this project consists mainly in supplying the orbit computed from DORIS, GPS and laser measurements.
Thanks to the development and the validation of the HY2 Processing Prototype based on the S-IGDR waveforms analysis, the HY2 data integration has been completed in the SSALTO/Duacs system in April 2014.
The data quality monitoring is routinely performed at CLS, as part of the CNES SALP (Système d'Altimétrie et Localisation Précise) project. The objective of this presentation consists in giving an overview of HY2 data coverage and data quality concerning altimeter parameters, but also the performances of delayed and real time products (GDR, IGDR) at mono-mission crossovers and along-track.
