Specify directory locations#

If on the ARM JupyterHub, it is recommended to create and specify a local directory that is outside of the COMBLE-MIP repository to upload raw model output files in your model’s format.

Processed domain-mean outputs are invited for commit to the GitHub repository on a user-specified branch under /comble-mip/output_scm/YOUR_MODEL_NAME/sandbox/YOUR_OUTPUT_FILE_NAME. These can be committed and removed at any time.

If you are able to make a run without ice, it is requested to append ‘noice’ to YOUR_OUTPUT_FILE_NAME, so that it can readily be automatically compared with the baseline and other liquid-only runs.
