The [[GFED4 biomass burning emissions|GFED4 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 2014.
 
The following inventories are now considered obsolete (but you may still use them for research purposes):

== 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>

Emissions by sector

Online emission of marine primary organic aerosol (POA)

This update was validated with 1-month benchmark simulation v11-01b and 1-year benchmark simulation v11-01b-Run0. This version was approved on 19 Aug 2015.

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 (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-α concentrations ([Chl-α]). 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 (Gantt et al., 2015).

Bug fix: Allocate the OCCONV array for marine POA simulations

This fix was included in v11-01j and approved on 03 Dec 2016

While unit testing GEOS-Chem with the GNU Fortran compiler, we discovered an error in the marine POA simulation. The array OCCONV should have been allocated in routine INIT_SEASALT (in module GeosCore/seasalt_mod.F) but wasn't. We have now added the following IF statement in GREEN, below the existing code: 

       IF ( AS /= 0 ) CALL ALLOC_ERR( 'DMID' )
       DMID = 0e+0_fp

      ! Allocate OCCONV only for marine-POA simulations (bmy, 10/13/16)
      IF ( Input_Opt%LMPOA ) THEN
         ALLOCATE( OCCONV( IIPAR, JJPAR, LLPAR ), STAT=AS )
         IF ( AS /= 0 ) CALL ALLOC_ERR( 'OCCONV' )
         OCCONV = 0e+0_fp
      ENDIF

This will only allocate OCCONV if we are doing a marine POA simulation.
