Biomass burning emissions

GFED2

02-Jan-2008

The fix described below for making 2006 the last available year of GFED2 data has now been implemented into GEOS-Chem v8-01-01. This will be released sometime in January 2008.

GFED2 8-day emissions are in the pipeline but have not yet been tested in any version of GEOS-Chem.

The previous benchmarked version (GEOS-Chem v7-04-12) is able to compute GFED2 biomass emissions from 1997-2005.

We have recently obtained the GFED2 C emissions data for the year 2006. In order to use the 2006 C emissions data to compute 2006 biomass emissions, then you must modify the following lines in the file "gfed2_biomass_mod.f":

       ! 2005 is currently the last year of available data
       IF ( YYYY > 2005 ) THEN
          YYYY = 2005
          WRITE( 6, 120 ) 
 120      FORMAT( 'YEAR > 2005; Using GFED2 biomass for 2005!' )
       ENDIF

to

     ! 2006 is currently the last year of available data
     IF ( YYYY > 2006 ) THEN
        YYYY = 2006
        WRITE( 6, 120 ) 
 120    FORMAT( 'YEAR > 2006; Using GFED2 biomass for 2006!' )
     ENDIF

NOTE: This fix has been added into GEOS-Chem v8-01-01. For the time being, if you need to use the 2006 GFED2 emissions in an earlier version than v8-01-01, then please apply the above changes to your research code.
