Abstract

NetCDF model output of the simulated sea surface height, surface passive tracer concentration, and model grid data from a West Antarctic Peninsula ROMS model.

Location: Coastal West Antarctic Peninsula

Methodology summary:

Model results are from a 1.5 km horizontal resolution Regional Ocean Modeling System (v3.6) circulation model, including dynamic sea-ice and static ice shelves (including mechanical and thermodynamic interactions between the floating ice shelves and the water underneath), for the West Antarctic Peninsula (WAP) coastal ocean.  The model simulation covers the period 2006-2012 and is forced by atmospheric output from the Antarctic Mesoscale Prediction System.  The results here are model sea surface height (for the entire simulation) and a surface passive tracer concentration for a temporal subset of the model run (1/25/2009-5/24/2009).  At a given time step during the model integration, a conservative tracer with a default value of 1.0 was placed throughout the entire vertical water column in any grid point shoreward of the model 0.08 m sea surface elevation anomaly (with respect to the long term mean over the model domain) contour along the WAP. This tracer was then allowed to freely advect and diffuse within the model domain based on the modeled circulation.

More details on these data are in Castelao et al. (2021), but the simulation is essentially the same (other than the new passive tracer) as in Graham et al. (2016).

This dataset includes three sets of data files:

1) NetCDF model output of the simulated sea surface height for the entire model simulation (2006 through 2012) of the West Antarctic Peninsula circulation model.  Each file (WAP_1k_zeta_00*.nc) contains 10 five-day temporal averages of the model SSH (m). See Data File WAP_1k_zeta_00_nc.tar.gz for file access.

2) NetCDF model output of the simulated sea surface height and surface passive tracer concentration for a temporal subset of the model run (1/25/2009 – 5/24/2009).  Each file (WAP_1k_avg_02*.ssh.dye.nc) contains 5 one-day averages of the model SSH (m) and surface passive tracer (dimensionless: 0-1). See Data File WAP_1k_avg_02_ssh_dye_nc.tar.gz for file access.

3) One file (WAP_1k_grid_r36_smooth_v5.nc) that contains the model grid data. See Data File WAP_1k_grid_r36_smooth_v5.nc for file access.
