CM2Mc is a coarse-resolution (3-degree) version of the GFDL coupled model. It is similar to CM2.1 and ESM2M, with larger biases. It includes the BLING biogeochemical module (both the published version, v0, and a developmental version with more functionality). The basic model is described by Galbraith et al., 2011. The code used here has been updated from the original publication (to the GFDL Siena release) and there are some small modifications to the runtime parameters as described in Galbraith and de Lavergne, 2019.

Simulation output is provided here, with no strings attached, in the hope that it might be useful for other investigators. Output can be used in publication, please just cite the description papers. If you have a burning question about anything, feel free to contact Eric. Otherwise, analyze away!

Model code

The source code used to generate the executable for these simulations is provided as a tar archive. Actually compiling and running the code is a bit difficult, since it requires computer-specific configuration and many ancillary files.   The compile script used is  provided below, but CM2Mc is included in the public GFDL distribution, which may be a better place to start from if you want to run the model.

Simulations

Equilibrium simulations. As described by Galbraith and de Lavergne, 2018.

Water hosing simulations. As described by Galbraith et al., 2016 and Brown and Galbraith, 2016.

Preindustrial control state. 12 GB tarball with output from last century of 3300 y spinup.

Thanks to Scinet (University of Toronto), the Canadian Foundation for Innovation, Compute Canada, and McGill University for providing the computational resources to conduct these simulations and make them available. Please email Eric with any questions, feedback or additional requests.
