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.

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.

If you are using HEMCO standalone on the Amazon Web Services EC2 cloud computing platform, then you will have access to an S3 bucket (s3://gcgrid/) with emissions inventories and meteorological data.

If you still need to download data for your HEMCO standalone simulation, we recommend using the bashdatacatalog tool. For more information, please see our Supplemental Guide entitled Manage a data archive with bashdatacatalog.
