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 the Jason-2 along-track sea level anomaly (SLA) data produced by Ssalto/Duacs and distributed by AVISO+, 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 (SARAL/AltiKa, CryoSat-2 and HY-2A).
