A high-resolution, 1-year, suite of 4D-Var Observing System Simulation Experiments of the East Australian Current System using the Regional Ocean Modeling System

This data is output from the Regional Ocean Modeling System (ROMS) simulations that comprise a suite of four 4D-Var Observing System Simulation Experiments (OSSEs) and one free-running simulation of the East Australian Current (EAC). The model has a horizontal resolution of 2.5-6 km in the cross shelf direction and 5 km in the along shelf direction, and 30 vertical s-levels. The model domain covers the southeastern Australia oceanic region from 25.1-41.5°S and 147.1-162.2°E, and the grid is orientated 20 degrees clockwise to be predominantly orientated alongshore. This zipped dataset contains model output, model forcing and configuration files and source code. The ROMS output is in the form of netcdf files. Each output file is a single data assimilation cycle (5-days), with daily averaged values. Each file contains the standard list of numerical output, including: zeta, ubar, vbar, ubar_eastward, vbar_northward, u, v, w, temp, salt, shflux, ssflux, sustr, svstr, as well as grid information. All variables in the netcdf are described with metadata. Also included are the ROMS configuration files (header and in files) required for setting up the simulations using the open-source, publically available ROMS v3.9 source code. A zip-file of the ROMS source code is included which when combined with the forcing and configuration files, can re-run the experiments. Forcing files are included for the Ref state experiment and OSSEs. Some data has been removed to reduce file size but full datasets can be obtained by contacting the authors.
