Japan Meteorological Agency (JMA) has been routinely operating an ocean data assimilation and prediction system for the western North Pacific (MOVE/MRI.COM-WNP*) developed by the Meteorological Research Institute (JMA/MRI) since March 2008. The operational system assimilates Jason-3, SARAL/AltiKa and CryoSat-2 along-track sea level anomaly (SLA) data from CMEMS, in addition to in situ temperature and salinity observations, and daily SST analysis (MGDSST**).
This poster will show the outline of MOVE/MRI.COM-WNP system and the impact of using additional SLA data (Sentinel-3A/B).
