Where can I get restart files for GEOS-Chem?

For instructions on how to obtain a set of sample restart files that you can use to spin up your own simulations, please visit this link.

Running GEOS-Chem

Please see our Running GEOS-Chem wiki page.

How long does GEOS-Chem take to run?

It depends on your particular computing environment. We have posted several timing results from GEOS-Chem 7-day time test simulations.

GEOS-Chem seems to be running too slowly. What can I do?

There are several ways to speed up a slow GEOS-Chem simulation.

If you are archiving many diagnostic quantities are a high temporal resolution (e.g. every hour), then this will increase the run time of your simulation. You can try saving out less diagnostic quantities, or archiving at a lower temporal resolution (e.g. every day).

GEOS-Chem errors

Please also see our Guide to GEOS-Chem error messages and Debug GEOS-Chem and HEMCO errors pages.

GEOS-Chem died with an error. What can I do?

Please see Understanding the different categories of errors section of our Guide to GEOS-Chem error messages.
