Product description

JMA uses real-time Argo data in two operational products: one for operational oceanographic analysis and forecast in the seas around Japan, Analyzed Oceanic Conditions, and the other for monitoring and predicting of ENSO (ODAS). The first product provides daily and monthly products for the seas around Japan and the Pacific Ocean. ODAS provides monthly analyses and indices for the equatorial Pacific and Indian Oceans.

Both systems assimilate a variety of data into their MOVE/MRI.COM system including subsurface temperature and salinity data and sea surface height data. The subsurface data comes from the GTS and is comprised of Argo floats, XBTs, XCTDs, TAO/TRITON array, and CTDs.

Ocean parameters

The following parameter outputs of the Analyzed Oceanic Conditions system for the seas around Japan can be found here:

• Daily subsurface temperatures
• Monthly mean subsurface temperatures

The following parameter outputs of the ODAS system can be found here:

• El Nino Monitoring Indices
• SST and SST anomalies
• Temperature and temperature anomaly cross sections
• Ocean heat content anomalies

The ODAS website has the current El Nino Monitoring Indices maps available for viewing.
