CAMX: CB4 mechanism, data requirements
For the CB4 chemical mechanism option in CAMx, data on the following
chemicals (species and groups) are required:
Species marked with (-) are reaction products of the primary emitted
species and are therefore not contained in the Emission Input files,
but are required for the initial concentrations,
upper and and lateral boundary concentrations file.
Input chemical species for the CB4 mechanism (not all are required):
- Inorganic species represented individually:
- NO Nitric oxide
- NO2 Nitrogen dioxide
- CO Carbon monoxide
- -N2O5 Dinitrogen pentoxide
- -HNO3 Nitric acid
- -HONO Nitrous acid
- -O3 Ozone
- -PNA Peroxynitric acid
- -H2O2 Hydrogen peroxide
- Organic species represented individually:
- ETH Ethene
- FORM Formaldehyde
- ISOP Isoprene
- MEOH Methanol
- ETOH Ethanol
- Organics species grouped together:
- PAR Paraffin carbon bond (C-C)
- OLE Olefin carbon bond (C=C)
- TOL Toluene and other monoalkyl aromatics
- XYL Xylene and other polyalkyl aromatics
- CRES Cresol and higher molecular weight phenols
- ALD2 Higher aldehyde (based on acetaldehyde)
- -PAN Peroxyacyl nitrate (based on peroxyacetyl nitrate)
- -NTR Organic nitrate (RNO3)
- -MGLY Methylglyoxal and other aromatic products
- -ISPD Isoprene product (lumped methacrolein, methyl vinyl ketone, etc.)
- -OPEN Aromatic ring opening product
- Additional chemical species for (optional) Aerosol Chemistry
