make_OM3_025deg_topo

Make 0.25-degree topog.nc MOM bathymetry file from the GEBCO 2024 dataset.

Workflow Overview

1. Generate Topography:
   Use ./gen_topog.sh to generate the topography and associated files. For 0.25-degree resolution or higher, this will require submission via qsub.

   First, add gdata for your project & working directory to the #PBS -l storage= line in get_topo.sh

   Then, use the qsub command to submit the script, passing the required input files as arguments. For example:

   qsub -v INPUT_HGRID="/path/to/ocean_hgrid.nc",INPUT_VGRID="/path/to/ocean_vgrid.nc",INPUT_GBCO="/path/to/GEBCO_2024.nc" -P $PROJECT gen_topo.sh

2. Finalize Output Files:
   Once the output files meet your satisfaction, commit and push the changes, then add the git commit hash as metadata in the output .nc files by running finalise.sh.

Note on Dependencies

This workflow relies on the xp65 conda environments for running the scripts and generating the outputs. As long as you are a member of the xp65 project, this conda environment is loaded as part of the scripts.
