GODAS: NCEP Global Ocean Data Assimilation System
GODAS is a real-time ocean analysis and a reanalysis. It is used for monitoring, retrospective analysis as well as for providing oceanic initial conditions for the CFS. Both temperature and synthetic salinity profiles are assimilated in a 3DVAR scheme. Beginning with March 2007, altimetry sea level is assimilated.
Many variables are created
Salinity is not good
Large biases in velocity fields
