On this page we shall answer some commonly asked questions about GEOS-Chem.
For new users
- I am a GEOS-Chem new user. What is expected of me?
- Where can I find user manuals for GEOS-Chem and related software?
- Can I use GEOS-Chem on cloud-computing platforms?
- What types of simulations can I run with GEOS-Chem?
- What is the horizontal resolution and vertical resolution of GEOS-Chem?
- Which meteorological data fields can be used by GEOS-Chem?
- To whom may I direct GEOS-Chem-related questions?
- What does the GEOS-Chem Steering Committee do?
- What do the GEOS-Chem Working Groups do?
- What does the GEOS-Chem Support Team do?
- I see that there are several GEOS-Chem email lists. How can I subscribe?
Science questions
Where can I find information about ...
- types of GEOS-Chem simulations that I can run?

- How many CPU cores may I use for my GEOS-Chem simulation?
- Why is GEOS-Chem not using all the CPU cores that I requested?
High-Performance GEOS-Chem (GCHP)
Please see the GCHP user manual at gchp.readthedocs.iofor more information.
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 the Run your simulation section of geos-chem.readthedocs.io..
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).
