SODA v2.0.4

Ocean data assimilation model

There are several versions of SODA (Carton, Giese and Grodsky, 2005), depending on the experiment setup. Version 2.0.4 replaces SODA 2.0.3 reanalysis addressing two issues. One issue has to do with the erroneous Argo data that came from WHOI. This data has been reprocessed. The reprocessed data is in the Atlantic Ocean, and so particularly for the Atlantic Ocean the new run should be used.
The second difference is that SODA 2.0.4 goes until December 2007, whereas SODA 2.0.3 only runs up to November 2005.
Version 2.0.3 & 2.0.4 uses QuikSCAT winds from 2000-2004. The ocean model is based on Parallel Ocean Program physics with an average 0.25x0.4x40-level resolution. Observations include virtually all available hydrographic profile data, as well as ocean station data, moored temperature and salinity time series, surface temperature and salinity observations of various types, and nighttime infrared satellite SST data. The output is in monthly-averaged form, mapped onto a uniform 0.5x0.5x40-level grid. The reanalysis provides three types of variables, those well constrained by observations, those partly constrained by dynamical relatioships to variables frequently observed, and those poorly constrained such as horizontal velocity divergence. It is worthy noting that SODA aims at improving upper ocean reanalysis, likely because data below 1000m is limited. For more information on the SODA product, see Carton et al. (2005) and Carton and Giese (2008).
