+When you have finished the analysis, it is a good idea to keep only the part of the model outputs that has been useful or may be useful in the future. You may delete test simulations that are obsolete and archive the rest (using cc_pack, tar, zip) on the storedir to diminish the environmental impact of mass storage.

 For example, the radiative transfer is usually the slowest part of the model, so you can potentially significantly accelerate simulations by reducing the frequency at which you call radiative transfer (by increasing the value of "iradia" in callphys.def).
-''Note: despite all your attention, if your experiments turn out to be bugged, the experimental design was inappropriate or some diagnostics are missing. These things happen, do not blame yourself too much, analyze your errors and you may rerun the simulations with the corrected experimental design or setup! High research quality remains what we aim for.''

 This guide, which was largely inspired from Earth IPSL climate models wiki page, provides good practices to reduce as much as possible the environmental footprints of simulations performed with our GCMs. We encourage you to go through the whole list of good practices below:
