== Anthropogenic emissions ==
== EDGAR v4.3 ==  


The EDGAR emissions of NOx, CO, and SOx are the standard emissions. However, the EDGAR emissions are typically overwritten by data from various [[Anthropogenic emissions#Regional inventories|regional emissions inventories]] listed on our [[Anthropogenic emissions]] wiki page.
The [[EDGAR v4.3 anthropogenic emissions|EDGAR v4.3 anthropogenic emissions inventory]] will be considered for inclusion in [[GEOS-Chem v11-02]].  These emissions will be read in via the [[HEMCO|HEMCO emissions component]].


The EDGAR inventory also includes [[#Ship emissions|emissions from ship exhaust]].

The EDGAR ship SO2 emissions are reported as per year.  Routine <tt>SEASCL_EDGAR_SHIP_SO2</tt> applies monthly scale factors (which are computed as the ratio of monthly/total ship SO2 emissions from the [[#Corbett|Corbett et al inventory]] to the annual EDGAR ship SO2 emissions.  This is required to impose aseasonality onto the EDGAR ship SO2 emissions.

== Use EDGAR v.4.1 in GEOS-Chem ==
 
EDGAR v4.1 emissions of CO, NOx and SO2 from 1970-2005 were prepared for GEOS-Chem model. It is available on a yearly basis with 1x1 degree spatial resolution. This inventory is not included in standard model yet but can be accessed here. It has been tested in GEOS-Chem v09-01-01 with 1-year full-chemistry benchmark for 2005.
 
To use EDGAR v.4.1 inventory, please download and the patch codes and data from the following URLs:
 
# http://166.111.42.46/EDGARV4.1_201111.zip
# http://166.111.42.46/Patch_EDGAR4_120702.zip
 
'''''NOTE''':'' for edgar_mod.f in the patch folder, please comment out line 1172 and 1173 in order to prevent double counting of international aviation for CO.
The patch folder contains 6 files: edgar_mod.f, biofuel_mod.f, input_mod.f, logical_mod.f, sulfate_mod.f, and input.geos. In input.geos, USE_EDGAR4 is a logical variable for user to choose EDGAR v.4.1 as anthropogenic emission inventory. Since biofuel emissions have been included in EDGAR v.4.1, if use EDGAR v.4.1, default biofuel emissions in GC model will be zero out automatically. If you would like to use shipping emissions from EDGAR v.4.1, also set LEDGARSHIP to True. Aircraft emissions in EDGAR v.4.1 were not implemented for NOx and SO2.
 
 
EDGAR v.4.1 emission data includes the following sectors.
 
;EDGAR_V41_IPCC_ 1A1_ENE:  Energy (fuel combustion).
;EDGAR_V41_IPCC _1A2_2:    Industry combustion and process emissions (fuel combustion).
;EDGAR_V41_IPCC_1A3b_c_e:  Ground Transport (road transport, rail transport and other transport, fuel combustion).
;EDGAR_V41_IPCC_1A3d1:     International shipping (fuel combustion).
;EDGAR_V41_IPCC_1A3d_SHIP:  Inland Waterways (fuel combustion).
;EDGAR_V41_IPCC_1A4_5:     Residential and other combustion (fuel combustion).
;EDGAR_V41_IPCC_1B:     Fuel production.
;EDGAR_V41_IPCC_6A_6C:     Solid Waste.
;EDGAR_V41_IPCC_7:     Other Sources.

== Implementation of EDGAR 4.2 into GEOS-Chem ==
 
EDGAR 4.2 emissions of NOx, CO, SO2, and NH3 from 1970-2008 were prepared and implemented into GEOS-Chem. Currently the implementation is based on version 9-01-02 and it will be done for version 9-02. This global emission inventory is added as a choice for users to use in GEOS-Chem simulation. Since shipping and aircraft emissions are included in EDGAR 4.2, global emission inventories for these two sources should not be selected to avoid double counting errors.
 
To use EDGAR 4.2 inventory, please download and the patch codes and data from the following URL: http://rain.ucis.dal.ca/upload/mli/
 
Please refer to the documentation for more details: http://rain.ucis.dal.ca/upload/mli/Documentation_EDGARinGEOSChem_20140403.pdf.
 
== Previous issues that are now resolved ==
 
=== Potential bug in EDGAR ship emissions code ===
 
'''''This update was tested in the 1-month benchmark simulation [[GEOS-Chem_v9-01-02_benchmark_history#v9-01-02s|v9-01-02s]] and approved on 5 Nov 2011.'''''
 
Michael Long discovered this potential bug in the EDGAR emissions code. 
 
The current GEOS-Chem default configuration uses the ICOADS ship emissions instead of the EDGAR ship emissions.  In routine <tt>READ_EMISSIONS_MENU</tt> in <tt>input_mod.f</tt>, we have a safety check...we turn off the logical switch <tt>LEDGARSHIP</tt> if switch <tt>LICOADS</tt> is turned on:
 
      !=================================================================
      ! Check global ship emissions options
      !=================================================================
      ! Add an ship emissions options (cklee, 6/30/09)
      ! Replace with ICOADS ship emissions
      ! User can still use regional EMEP, and ARCTAS-SO2 if he wants (phs)
      IF ( LICOADSSHIP ) THEN
        LEDGARSHIP = .FALSE. ! ICOADS precedes EDGAR
        LSHIPSO2  = .FALSE. ! SO2-ICOADS precedes SO2-Corbett
      ENDIF   
 
In <tt>edgar_mod.F</tt>, the EDGAR ship emissions arrays are not allocated if the switch <tt>LEDGARSHIP == .FALSE.</tt>:
 
      IF ( LEDGARSHIP ) THEN
        ALLOCATE( EDGAR_SO2_SHIP( IIPAR, JJPAR ), STAT=AS )
        IF ( AS /= 0 ) CALL ALLOC_ERR( 'EDGAR_SO2_SHIP' )
        EDGAR_SO2_SHIP = 0d0
        ALLOCATE( EDGAR_NOx_SHIP( IIPAR, JJPAR ), STAT=AS )
        IF ( AS /= 0 ) CALL ALLOC_ERR( 'EDGAR_NOx_SHIP' )
        EDGAR_NOx_SHIP = 0d0
        ALLOCATE( EDGAR_CO_SHIP( IIPAR, JJPAR ), STAT=AS )
        IF ( AS /= 0 ) CALL ALLOC_ERR( 'EDGAR_CO_SHIP' )
        EDGAR_CO_SHIP = 0d0
 
      ENDIF
 
However, we still pass <tt>EDGAR_CO_SHIP</tt> to routine <tt>COMPUTE_EDGAR_CO</tt> even if it is not allocated:
 
        IF ( LEDGARCO ) THEN
            CALL COMPUTE_EDGAR_CO( YEAR, EDGAR_CO, EDGAR_CO_SHIP )
        ENDIF
 
Here, <tt>EDGAR_CO_SHIP</tt> is an output variable, which is supposed to return the EDGAR ship emissions at the current model resolution.  This may produce undefined behavior.  This may trigger an error when compiling with the check-array-bounds option (<tt>BOUNDS=yes</tt>).
 
Some of the more forgiving compilers may "fix" this on-the-fly and thus, you might not see any errors.  However, for the sake of good programming practice, this should be fixed.

=== Typos in edgar_mod.f ===
 
'''''NOTE: This issue was resolved in [[GEOS-Chem v9-01-01]].'''''
 
In routines <tt>READ_C2H2</tt> and <tt>READ_C2H4</tt> of <tt>edgar_mod.f</tt>, the data directory was wrongly listed as <tt>EDGAR200607</tt> instead of <tt>EDGAR_200607</tt>.  We have now fixed these typos in v9-01-01.
