These four files are the model configurations as well as model grids for the SP and MR model mentiond in the manuscript titled with "Impact of Horizontal Resolution (Submesoscale Permitting vs Mesoscale Resolving) on Ocean Dynamic Features in the South China Sea", which would be potentially published in the Journal of Earth and Space Science. With the model grids and publicly available forcing field data introduced in the MS, it is easy to generate model input files. Finally, with the configuration files (e.g., .h, .in ), one can easily reproduce all the model results.
