− | === Baseline inventory ===
| + | |
− | | + | |
− | By default, GEOS-Chem uses the [[Anthropogenic emissions#GEIA/Piccot|GEIA/Piccot]] inventory with 10 gas-phase species:

− | === Optional inventories ===
| + | |
− | | + | |
− | It is the usual practice to replace the NOx, CO, and SOx from the [[Anthropogenic emissions#EDGAR|global EDGAR emissions inventory]] with data from the [[Anthropogenic emissions#GEIA/Piccot|GEIA/Piccot]] inventory.
| + | |
− | | + | |
− | These emissions may be further overwritten by one or more [[Anthropogenic emissions#Regional inventories|regional emissions inventories]] in various locations of the globe (e.g. N. America, Asia, Europe, etc.).
| + | |
− | | + | |
− | === Anthropogenic emissions of aerosols ===
| + | |
− | | + | |
− | Several aerosol species have anthropogenic emissions. Please see our [[Aerosol emissions#Anthropogenic emissions|aerosol emissions page]] for more information about these inventories.
| + | |
− | | + | |
− | === Annual scale factors ===
| + | |
− | | + | |
− | Several of the emission inventories are for a particular year or range of years. To obtain emissions for years outside of the given range, [[Scale factors for anthropogenic emissions|interannual scale factors must be applied]].
| + | |
− | | + | |
− | == Biofuel emissions ==
| + | |
− | | + | |
− | GEOS-Chem emits the same 12 species as for [[Anthropogenic emissions|anthropogenic emissions]] listed above. The default inventory is that of [[Biofuel emissions#Yevich and Logan|''Yevich and Logan'' <nowiki>[2003]</nowiki>]]. This inventory can be overwritten by:
| + | |
− | | + | |
− | * [[EPA/NEI99 North American emissions|EPA/NEI99 biofuel emissions]] over N. America
| + | |
− | * [[Anthropogenic emissions#David Streets|David Streets et al 2006 biofuel emissions]] over SE Asia
| + | |

− | == Biogenic emissions ==

− | === GEIA ===
| + | |
− | | + | |
− | By default, GEOS-Chem emits the following species from the [[Biogenic emissions#GEIA|GEIA biogenic emissions inventory]]:

− | #Monoterpenes

− | #Methyl Butenol

− | == Biomass burning ==
| + | |
− | | + | |
− | By default GEOS-Chem uses 15 biomass burning species from [http://acmg.seas.harvard.edu/publications/duncan2002a.pdf ''Duncan et al'' <nowiki>[2003]</nowiki>]:
| + | |

− | # NOx

| + | |
− | # BC
| + | |
− | # OC
| + | |
− | # CO2 (NOTE: for offline simulations only!)
| + | |
− | | + | |
− | Most of these are also [[#Anthropogenic emissions|anthropogenic emissions species]].
| + | |
− | | + | |
− | All of these species can be overwritten by [[Biomass_burning_emissions#GFED2|GFED2 monthly, 8-days, or 3hr biomass emissions]].
