...

• readonly CHECKOUT="20210205": date the code was checked out on in the form {year}{month}{day}. The source code will be checked out in sub-directory named {year}{month}{day} under <code_source_dir>.

• readonly BRANCH="master": branch the code was checked out from. Valid options include “master”, a branch name, or a git hash.

• readonly DEBUG_COMPILE=false : option to compile with DEBUG flag (leave set to false)

# Run options

For a short test run, this section might look like:

...

• build: all the stuff to compile. The executable is also there (e3sm.exe) is also there.

• case_scripts: the files for your particular simulation.

• run: where all the output will be. Most components (atmosphere, ocean, etc.) have their own log files. The coupler exchanges information between the components. The top level log file will be of the form run/e3sm.log.*. Log prefixes correspond to components of the model:

  • atm: atmosphere

  • cpl: coupler

  • ice: sea ice

  • lnd: land

  • ocn: ocean

  • rof: river runoff

...

To post-process a model run, do the following steps. Note that to post-process up to year n, then you must have short-term archived up to year n.

cd <post_processing_script_dir>

Configuration File

Create a new configuration file or copy an existing one. Call it <case_name>.cfg.

...

• <e3sm_simulations_dir>/<case_name>/post/atm/180x360_aave/ts/monthly/10yr has the time series files – one variable per file, in 10 year chunks as defined in <post_processing_script_dir>/<case_name>.cfg.

• <e3sm_simulations_dir>/<case_name>/post/atm/180x360_aave/clim/20yr similarly has climatology files for 20 year periods, as defined in <post_processing_script_dir>/<case_name>.cfg`.

• <e3sm_simulations_dir>/<case_name>/post/atm/glb/ts/monthly/10yr has globally averaged files for 10 years periods as defined in <post_processing_script_dir>/<case_name>.cfg. The glb directory currently doesn't follow the same file naming convention as 180x360_aave.

...

Your diagnostics are located at the web address corresponding to the www path in <post_processing_script_dir>/<case_name>.cfg.

See the “Global time series” section above for finding the relevant web links. Fill the table with the specific web links: e.g., https://web.lcrc.anl.gov/public/e3sm/diagnostic_output/<username>/E3SM/v2/beta/<case_name>/e3sm_diags/180x360_aave/model_vs_obs_0001-0020/viewer/.
