Description of coupler
Colin Thackray wrote the The coupler is a Python interface to pass that passes information between the MITgcm ocean and GEOS-Chem atmosphere, allowing you to capture the temporal dynamics of air-sea exchange. The coupler was initially developed as part of a project to model the global fate and transport of polychlorinated biphenyls (PCBs), a semi-volatile industrial chemical. Conceptually, here's the sequence of events being handled by the coupler:
- run the ocean forward one time step
- calculate evasion to the atmosphere
- save evasion flux to file
- pause
- regrid evasion file
- passes evasion file to the atmosphere
- run the atmosphere forward one time step
- calculate deposition to ocean and new atmospheric concentrations
- save deposition and atmospheric concentration to file
- pause
- regrid deposition and concentration files
- pass file to ocean
- run the ocean forward one time step
- repeat...
