NCEP Global Ocean Data Assimilation System (GODAS)

Description

The GODAS dataset 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 designed by Derber and Rosati (1989). 40 vertical levels are in the model together with 1x1 data values (enhanced in resolution to 1/3x1/3 degrees latitude within 10 degrees of the equator). The data is provided at 1/3x1/3 degrees for all latitudes. The GODAS is forced by the momentum flux, heat flux and fresh water flux from the NCEP atmospheric Reanalysis 2.
