MOM and ROMS model output from Antarctic bottom layer temperature advection experiments v1.0

Full description

This dataset contains ocean temperatures and velocity anomalies from idealized wind perturbation experiments resembling a shift towards a positive Southern Annular Mode. Data is provided for two global ocean sea-ice models using the Modular Ocean Model (MOM) at 1/4° horizontal resolution (MOM025; 50 vertical levels) and 1/10° horizontal resolution (MOM01; 75 vertical levels). It also contains velocity anomalies from the same wind perturbation experiment in a single-layer shallow water model using the Regional Ocean Modelling System (ROMS) at 1/4° horizontal resolution. The ROMS zonal and meridional velocity fields, U and V, cover a one-year period with a 0.5 day temporal resolution. Barotropic U and V fields for MOM025 are given at a 5 daily temporal resolution (over a one-year period) and a subset of the MOM01 U and V fields are given at a 6 hourly temporal resolution. Temperature fields, T, are calculated from the average of the annual (MOM01) and seasonal (MOM025) 10 member ensembles from the respective model mean-states.
