Surface North Atlantic MOM5-TOPAZ outputs derived from a regular hindcast and a robust diagnostic simulation experiment from 1980-01-01 to 2017-12-31 (NCEI Accession 0283628)

This dataset contains monthly surface outputs derived from a 0.25 degree resolution MOM5-TOPAZ model configuration for the North Atlantic. The outputs include results from two experiments: (i) Regular hindcast, and (ii) Robust Diagnostic Simulation (RDS). In these experiments, the initial and boundary conditions were derived from the SODA 3.12.2 ocean reanalysis product for temperature and salinity, and a Global MOM5-TOPAZ model for the biogeochemical tracers. Surface forcing of momentum, heat, and freshwater were derived from the JRA55-do-1-5-0 atmospheric reanalysis product using bulk parameterization. In the RDS, the simulated temperature and salinity fields were restored to the monthly SODA 3.12.2 values. To this effect, a relaxation coefficient of 7 days was used in the upper 500 m, and 365 days below 500 m.
