Data access

The 3-D ISAS13 monthly fields and climatology are delivered in NetCdf format.

Monthly fields

The 3-D monthly fields of temperature and salinity in NetCdf format can be found at the following DOI reference:

Fabienne Gaillard (2015). ISAS-13 temperature and salinity gridded fields. Pôle Océan.


A climatology has been produced as the mean over the period 2004-2012. Temperature, salinity and mixed layer depth  can be found at the following DOI reference:

Fabienne Gaillard (2015). ISAS-13-CLIM temperature and salinity gridded climatology. Pôle Océan.

Near Real Time extension

Coriolis runs the ISAS tool in real time. Those fields can be used to extend the ISAS13 realanalysis toward the most recent periods.

Temperature and salinity fields from Near real Time analysis (2010-present) be accessed using FTP :
