Download input data

Before starting a HEMCO standalone simulation, make sure that all of the relevant emissions and meteorology that you will need for your simulation are present on disk.

Tip

If you are located at an institution where there are several other HEMCO and/or GEOS-Chem users, then data for HEMCO standalone might already be located in a shared folder. Ask your sysadmin or IT staff.

The GEOS-Chem Input Data portal is the main source of emissions and meteorology simulations. This data, which is curated by the GEOS-Chem Support Team at Washington University in St. Louis, is stored an Amazon Web Services S3 bucket named s3://geos-chem. You can easily download the data from there to your computer cluster or AWS EC2 cloud instance.

You can use a couple of different methods to download data. Click on one of the links below for more information.

• Download data with a dry-run simulation
• Manage a data archive with bashdatacatalog
• Download data with Globus
