Post-doctoral spring onset research

Idealplanets Overview

This repo is for running aquaplanet and drycore simulations with CESM on Cheyenne.

Initialization

After following the installation instructions here:

Edit environment configuration:

cd spring_onset
cp idealplanets/environment/config.py my_config.py
vim my_config.json

Configuration can be in either .py or .json format. Follow the required variables from config.py. Easiest is just to edit the my_config.py file and not convert to json.

cd spring_onset
bash ./go.sh

This go script kicks off scripts from the scripts directory and requires the my_config.py file. Pip has trouble installing PyNIO so this package may need to be installed manually with conda.

Preprocessing

idealplanets/preprocessing/inject_anomaly.py is used to inject a heat anomaly or change in phi into an sst file or topo file. This script can inject disk and band type heat anomalies. Parameters are specified through the command line using the argparse module.

Postprocessing

idealplanets/postprocessing/plot_field.py is used to visualize output from the aquaplanet simulations.

Simulation

.F90 files from cesm_mods need to be copied into $CASEDIR/SourceMods/src.cam and namelist_definition.xml needs to be in $CESM/components/cam/bld/namelist_files/

run_cesm.py runs the aquaplanet/drycore simulation using parameters specified through the argparse module.

run_pipeline.py injects a heat anomaly, runs the aquaplanet simulation, and can run both visualization scripts. Parameters are again specified through the argparse module.

run_batch.py can be used to run multiple CESM instances at the same time.
