On this page, we provide a list of species included in GEOS-Chem v11-01 and later versions.

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:

Legend

The tables in the following sections list the species used in each of the various GEOS-Chem simulations. Several categories—corresponding to fields of the GEOS-Chem species database—are displayed. Note that some categories are only appropriate to full-chemistry simulations.

For the sake of clarity, we have omitted several species properties (i.e. Henry's law constants, dry deposition parameters, rainout & washout parameters, etc.). For a complete list of these properties, please see our Physical properties of GEOS-Chem wiki page.

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.

Some hydrocarbon species are carried in equivalent carbon atoms. For these species, the molecular weight of carbon (12) will be listed along with the number of carbon atoms (1C, 2C, 3C, etc) per species.

Species for which no molecular weight is displayed are non-advected species. These have lifetimes so short that they never move away from the grid box in which they are produced.

Gas or Aer Denotes whether the species is in the gas or aerosol phase. This determines how the species dry deposits and/or wet deposits.
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?

If not, then the species will have its chemistry or loss performed outside of the KPP solver (e.g. in the aerosol modules).

Mechanisms Displays the GEOS-Chem 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 Shows the number of molecules of the species that will be included in the computation of the P(Ox) and L(Ox) diagnostic families.

NOTES:

  1. HNO3 dry-deposits like a gas, but wet-deposits like an aerosol. Therefore, in the GEOS-Chem species database, we give HNO3 both gas and aerosol parameters.

Additional species for marine POA simulations

Full-chemistry simulations using emissions of marine primary organic aerosol (POA) carry the following additional species:

Species Full name Molec wt
(g/mol)
Gas or Aer Advect Drydep Wetdep
MOPI Hydrophilic marine organic carbon 12, 1C Gas X
MOPO Hydrophobic marine organic carbon 12, 1C Gas X

NOTES:

  1. As of v11-01k, both MOPI and MOPO were defined with the Is_GAS = T attribute in the GEOS-Chem species database. This flag determines whether the species should dry deposit and/or wet deposit like a gas or an aerosol. This might have been a bug in the v11-01 code. But since neither MOPI nor MOPO wet-deposit nor dry-deposit, then perhaps this bug does not have any effect. We shall correct this during the GEOS-Chem v11-01 provisional release period.

TOMAS aerosol microphysics

There are currently 4 options for TOMAS aerosol microphysics simulations:

Option Description Compile with
TOMAS12 Uses 12 size bins (nn = 12) TOMAS12=y
TOMAS15 Uses 15 size bins (nn = 15) TOMAS15=y
TOMAS30 Uses 30 size bins (nn = 30) TOMAS30=y
TOMAS40 Uses 40 size bins (nn = 40) TOMAS40=y


TOMAS aerosol microphysics simulations carry the same species as the Tropchem simulation, plus the additional size-resolved aerosol species:

Species Full name Molec wt
(g/mol)
Gas or Aer Advect Drydep Wetdep
AW{1..nn} Aerosol water, size bins 1 - nn 18 Aer X
DUST{1..nn} Mineral dust, size bins 1 - nn
  • NOTE: These are carried in place of DST1, DST2, DST3, DST4
100 Aer X X
ECIL{1..nn} Hydrophilic elemental carbon, size bins 1 - nn 12 Aer X X
ECOB{1..nn} Hydrophobic elemental carbon, size bins 1 - nn 12 Aer X
H2SO4 Sulfuric acid 98 Gas[1] X X X
NK{1..nn} Aerosol number, size bins 1 - nn 1 Aer X X X
OCIL{1..nn} Hydrophilic organic carbon, size bins 1 - nn 12 Aer X X
OCOB{1..nn} Hydrophobic organic carbon, size bins 1 - nn 12 Aer X X
SF{1..nn} Sulfate aerosol, size bins 1 - nn 96 Aer X X
SS{1..nn} Sea salt aerosol, size bins 1 - nn 58.5 Aer X X

NOTES:

  1. The TOMAS H2SO4 species dry-deposits like a gas, but wet-deposits like an aerosol. Therefore, we need to give H2SO4 both gas-phase and aerosol parameters in the GEOS-Chem species database.
