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_les/YOUR_MODEL_NAME/sandbox/YOUR_RUN_NAME. These can be committed and removed at any time.

It is requested to name your baseline small-domain run directory as ‘Lx25km_dx100m’ (in place of YOUR_RUN_NAME), so that it can readily be automatically compared with other runs using the same test specification.

# specify start time of simulation and simulation name
start_dtime = '2020-03-12 22:00:00.0'
