On this page we describe the directory tree from which the HEMCO emissions component can read emissions inventories and other atmospheric data sets.


The HEMCO emissions component can read several types of emission inventories, as well as other types atmospheric data sets, such as production and loss rates, or concentration data. We have collated all of this data into a comprehensive directory tree structure. Each folder of the HEMCO data directory tree represents a particular emissions inventory or other data set.

At present, the HEMCO data directory tree resides on the Compute Canada and AWS s3://gcgrid bucket. We have created a package that will let you download this directory tree to your local disk storage space. For more information, please see the Downloading the HEMCO data directories section below.

Data directories by GEOS-Chem version

Our repository named input-data-catalogs contains lists of input files needed to run GEOS-Chem simulations. These are contained in the comma-separated files ChemistryInputs.csv, EmissionInputs.csv and InitialConditions.csv. Passing these files to the bashdatacatalog utility will download the data to your local disk storage].
