Species in GEOS-Chem
On this page, we provide a list of species included in GEOS-Chem v11-01 and later versions.
Contents
Overview
In GEOS-Chem v11-01 and higher versions, the distinction between tracers and species has been eliminated. We can now speak of everything as a "species". Those species that are moved around by the winds and convective mass fluxes—which were formerly called "tracers"—are now referred to as "advected species".
Please see the following resources for general information about how species are defined in GEOS-Chem:
- Physical properties of GEOS-Chem species
- GEOS-Chem species units
- GEOS-Chem species database
- Adding new species
- Adding passive species to GEOS-Chem
- Species indexing in GEOS-Chem

Legend
The tables in the following sections contain these categories. Note that some categories are only appropriate to full-chemistry simulations.
Item | Description |
---|---|
Species | Abbreviated name of the species. This will be the variable name corresponding to the species in netCDF restart and output files. |
Full name | A longer, descriptive name for the species. This will be saved to netCDF restart and output files under the long_name variable attribute. |
Molec wt | Molecular weight of the species in g mol-1. |
Advect | Is the species subject to advection, cloud convection, and boundary layer mixing? |
Drydep | Is the species subject to dry deposition? |
Wetdep | Is the species soluble and subject to wet deposition? |
The following quantities are only relevant for full-chemistry simulations: | |
Formula | Chemical formula of the species. |
Chem | Is the species contained in one of the pre-built KPP chemistry mechanisms used by GEOS-Chem? |
Mechanisms | Lists all of the chemistry mechanisms to which the species belongs. |
Photol | Is the species included in the FAST-JX photolysis mechanism? |
Structure | A graphic showing the molecular structure of the species. |
Ox | Is the species included in the computation of the P(Ox) and L(Ox) diagnostic families? The value displayed represents the number of molecules included in the prod/loss family. |

Full-chemistry
The following table lists the species in the full-chemistry simulations. (NOTE: We will add the remaining chemical structure diagrams shortly.)
NOTES:
- Several hydrocarbon species are carried as as atoms C instead of molecules per species. We assign these species a molecular weight of 12 g/mole and also specify the number of moles C per moles species.
