SODA POP v1.4.3

Ocean data assimilation model

There are several versions of SODA (Carton, Giese and Grodsky, 2005), depending on the experiment setup. Version 1.4.3 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).
