This dataset includes the output from idealized primitive equation MOM6 simulations, and is useful for studying ocean mesoscale turbulence over a hierarchy of grid resolutions (1/4, 1/8, 1/16, 1/32 degree). The model has intermediate complexity, incorporating basin-scale geometry with idealized Atlantic and Southern oceans, and with non-uniform ocean depth to allow for mesoscale eddy interactions with topography. The model is perfectly adiabatic and spans the equator, and thus fills a gap between quasi-geostrophic models, which cannot span two hemispheres, and idealized general circulation models, which generally have diabatic processes and buoyancy forcing. The dataset includes a total of 8 experiments because the simulations were run with two different depths over which the wind stress was applied (hmix = 5 and 20 m)

Data Description:

File format: netCDF3

Total volume: 20 TB

Temporal resolution:

Experiments with HMIX=5 m 1/4 degree simulations were run for 32,000 days; 1/8 degree simulations were run for 5000 days; 1/16 degree simulations were run for 5000 days; 1/32 degree simulations were run for 2800 days;

Experiments with HMIX=20 m 1/4 degree simulations were run for 32,000 days; 1/8 degree simulations were run for 6000 days; 1/16 degree simulations were run for 6000 days; 1/32 degree simulations were run for 2900 days;

Each experiments has the following files:

• averages_*.nc (holds 5-day averages); one file per 500 days for the resolutions 1/4, 1/8, 1/16; one file per 100 days for the resolution 1/32;

• snapshots_*.nc (holds snapshots at 5-day frequency); one file per 500 days for the resolutions 1/4, 1/8, 1/16; one file per 100 days for the resolution 1/32;

• longmean_.nc (holds 100-day averages, but over a longer time period than averages_.nc and snapshots_*.nc); one file per 2000 days for the resolutions 1/4, 1/8; one file per 1000 days for the resolution 1/16; one file per 200 days for the resolution 1/32;

• static.nc (holds the horizontal grid information);

• ocean_stats.nc (holds time series of domain-integrated metrics computed online, e.g., available potential energy and kinetic energy);

• restart files (so users can pick-up and extend the runs)
