View source for Aerosol emissions

This page contains links to the relevant pages which detail the aerosol emissions inventories used by GEOS-Chem.

== Anthropogenic emissions ==

Please see the following pages for more information:

# [[Sulfate aerosols#Source code and data|Sulfate aerosols: Source code and data]]
# [[Aircraft_emissions#SO2|Aircraft emissions: SO2]]
# [[Scale factors for anthropogenic emissions]]

== Biofuel and natural-source emissions == 

The sulfate simulation uses NH3 biofuel and natural-source emissions from GEIA.  For more information please see our [[Sulfate aerosols#Source code and data|sulfate aerosols wiki page]].

== Biomass burning emissions ==

The [[Biomass burning emissions#GFED3|GFED3 inventory]] can be used to compute biomass burning emisisons for the following species:

#SO2
#NH3
#EC = elemental carbon (aka "black carbon")
#OC = organic carbon

for the years 1997 thru 2011.  The older ''Duncan et al'' [2003] seasonal and interannual biomass emissions (cf ''Bey et al'' [2001]) may also be used; however, these are considered to be of ancient vintage.

== DMS emissions ==

From [http://acmg.seas.harvard.edu/publications/2004/park2004.pdf ''Park et al'' <nowiki>[2004]</nowiki>]:

<blockquote>The oceanic emission of DMS is calculated calculated as the product of local seawater DMS concentration and sea-to-air transfer velocity. The seawater DMS concentrations are gridded monthly averages from Kettle et al. [1999], and the transfer velocity of DMS is computed using an empirical formula from Liss and Merlivat [1986] as a function of the surface (10 m) wind speed.</blockquote>

== EC and OC emissions ==

The following emissions inventories for elemental carbon (EC) and organic carbon (OC) are used in GEOS-Chem.

# [[Carbonaceous aerosols#EC_and_OC_emissions|''Bond et al'' <nowiki>[2007]</nowiki>: EC and OC emissions over North America]]
# [[Carbonaceous_aerosols#Oceanic_OC_emissions|''Spracklen et al'': Oceanic OC emissions]] '''''(NOTE: to be included post [[GEOS-Chem v8-03-01]])'''''

== Mineral dust emissions ==

The [[Mineral_dust_aerosols#Overview|mineral dust emissions algorithm]] is described on a separate wiki page.

== Sea salt emissions==

Please see this discussion about [[Sea salt aerosols#Updates to sea salt emissions algorithm|recent updates to the sea salt aerosol emissions]].

== Ship emissions ==

Please see our [[Ship emissions|ship emissions wiki page]] for a full description of the SO2 ship emission inventories that are available for use in GEOS-Chem.

== Volcanic emissions ==

Please see our [[Volcanic SO2 emissions from Aerocom]] wiki page.

== Online emission of marine primary organic aerosol (POA) ==

'''''[https://earthscience.arc.nasa.gov/person/Matthew_S_Johnson Matthew Johnson] wrote:'''''

:The online emission parameterization for sub-micron marine primary organic aerosol (POA) was developed for implementation into GEOS-Chem at North Carolina State University ([http://www.atmos-chem-phys.net/12/8553/2012/acp-12-8553-2012.html Gantt et al., 2012]).  The wind speed dependent size-resolved parameterization calculates the organic mass fraction of sea spray aerosol under varying levels of surface ocean chlorophyll-''&alpha;'' concentrations ([Chl-''&alpha;'']).  The parameterization was designed to be used for all global and regionally nested spatial resolutions and was tested in [[GEOS-Chem v9-02]].  The submicron marine POA emissions proved to improve the model-predicted concentrations of total organic aerosol concentrations over coastal and marine regions ([http://www.geosci-model-dev.net/8/619/2015/gmd-8-619-2015.html Gantt et al., 2015]).
