| + | |
| − | | + | |
| − | 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.

| − | 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.

| + | |
| − | | + | |
| − | '''''NOTE: The implementation of EDGAR 4.2 into GEOS-Chem will be done via the [[HEMCO|HEMCO emissions component]], slated for [[GEOS-Chem v10-01]].'''''
| + | |
| − | | + | |
| − | 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 added into the standard GEOS-Chem in [[GEOS-Chem v10-01|v10-01]]. 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.

| − | === 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.

| + | |
| − | | + | |
| − | 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.
