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:

  1. Sulfate aerosols: Source code and data
  2. Aircraft emissions: SO2
  3. 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 wiki page.

Biomass burning emissions

The GFED3 inventory can be used to compute biomass burning emisisons for the following species:

  1. SO2
  2. NH3
  3. EC = elemental carbon (aka "black carbon")
  4. 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 Park et al [2004]:

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.

EC and OC emissions

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

  1. Bond et al [2007]: EC and OC emissions over North America
  2. Spracklen et al: Oceanic OC emissions (NOTE: to be included post GEOS-Chem v8-03-01)

Mineral dust emissions

The mineral dust emissions algorithm is described on a separate wiki page.

Sea salt emissions

Please see this discussion about recent updates to the sea salt aerosol emissions.

Ship emissions

Please see our 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.
