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.

Latest revision as of 14:00, 2 November 2016

On this page we provide information about the Emissions Database for Global Atmospheric Research (EDGAR) anthropgenic emissions inventories used in GEOS-Chem.

EDGAR v4.3

The 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 emissions component.

--Melissa Sulprizio (talk) 13:53, 2 November 2016 (UTC)

EDGAR v4.2

The EDGAR v4.2 anthropogenic emissions inventory was introduced into GEOS-Chem v10-01. These emissions are read in via the HEMCO emissions component. All older instances of the EDGAR emissions have been removed from GEOS-Chem v10-01 and newer versions.

--Bob Y. 12:11, 13 February 2015 (EST)

EDGAR v4.1

Qiang Zhang provided instructions on how to add the EDGAR v4.1 anthropogenic emissions inventory into GEOS-Chem as a research option. But EDGAR 4.1 was never adopted as a standard GEOS-Chem emissions inventory.

--Bob Y. 12:09, 13 February 2015 (EST)

EDGAR v3

The EDGAR v3 anthropogenic emissions inventory was retired from GEOS-Chem v10-01.
