This page describes where you can obtain the GEOS-Chem source code and required data files.
Overview
In addition to the files contained in the run directories, GEOS-Chem also needs to access data directories containing:
- Meteorological data (a.k.a. the "met fields) used to drive GEOS–Chem
- Emissions inventories used by GEOS-Chem
- Scale factors used to scale emissions from a base year to a given year
- Sample restart files that you can use to spin up your GEOS-Chem simulations
- Oxidant (OH, O3) concentrations for both full-chemistry and offline simulations
- Other GEOS–Chem specific data files.
These files are often too large to store in a single user's disk space. Therefore, they are meant to be stored in shared disk space where all GEOS-Chem users in your group can have access to them.
The GEOS–Chem shared data directories may be downloaded from the following locations:
| Archive | Location | Description | How to download? |
|---|---|---|---|
| Compute Canada | http://geoschemdata.computecanada.ca | This is the main GEOS-Chem data archive.
|
|
| Amazon Web Services S3 storage | s3://gcgrid | This is an AWS S3 bucket containing a mirror of the Harvard University storage server. It will not contain the complete record of met fields, but additional data may be added by submitting a request to the GCST.
See our cloud computing tutorial (cloud.geos-chem.org) for more information.
