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 models (free-running and data assimilating) used to produce this output are described in Gwyther, D., Kerry, C., Roughan, M., and Keating, S. R. et al (submitted). The free-running simulation is similar to presented in https://doi.org/10.26190/TT1Q-NP46, while the data assimilating model is similar to that presented in: https://doi.org/10.26190/5ebe1f389dd87 ...
