The reanalysis data is packaged into monthly means from January 1958 to December 2008 (although five day means are also available) and stored in [[NetCDF]] format. Standard state variables were calculated including temperature, salinity, zonal and meridional velocities, and sea level, as well as several derived fields such as heat content. Finalized data was remapped from the displaced pole grid to a uniform horizontal grid with 0.5°x0.5° horizontal resolution and 40 vertical layers with 10-meter vertical resolution near the surface.<ref name=cg2008/>

In addition to the 61-year reanalysis data set, a “beta” version (i.e., currently being evaluated), SODA 2.2.4, was released in 2010 and extends from 1871 to 2008 with monthly temporal resolution. This extended analysis is identical in horizontal and vertical spatial resolution as the standard reanalysis data set (SODA 2.1.6), and includes similar output variables.<ref name=IRIDL>IRI Data Library, 2012.
