Colin Thackray wrote the Python interface to pass information between the MITgcm and GEOS-Chem.
Code credit: Colin Thackray (MIT) and Helen Amos (Harvard)
Tested for the following model versions
- MITgcm ECCOv4 (lat-lon-cap grid configuration) PCB simulation
- GEOS-Chem v9-01-03 PCB simulation
Prerequisites for running the coupler
- An account on Odyssey or Svante
- Space on a file/storage server
- A copy of GEOS-Chem that compiles and runs standalone (i.e., not as part of the coupler)
- A copy of the MITgcm that compiles and runs standalone (i.e., not as part of the coupler)
Step 1: Download the coupler
The coupler will run GEOS-Chem and MITgcm together, generating large output files from both models. Clone a copy of the coupler from Colin's GitHub page.
git clone https://github.com/thackray/coupler.git
Step 2: Initial set up. On Svante, set up the coupler with the following commands. You should be logged in to the head node.
cd /your_directory/coupler
ssh -Y username@svante2.mit.edu (ssh to a file server)
python setup.py
exit (go back to head node)
csh
chmod 755 startup.sh
./startup.sh
exit
ssh -Y username@svante2.mit.edu (ssh to a file server)
python example.py
