Files:
------
scalefoss.liq.2x25.1985 : Liquid fuel scale factor files for years
scalefoss.liq.2x25.1986 :  1985 thru 1998.  These are used to scale
scalefoss.liq.2x25.1987 :  the anthropogenic CO and hydrocarbon species
scalefoss.liq.2x25.1988 :  from the baseline emissions year of 1985 
scalefoss.liq.2x25.1989 :  to subsequent years.

All files are in the following binary format:

	IMX, JMX
	ARRAY(81,67)

where IMX and JMX are INTEGERs (longwords in IDL)
      ARRAY       is  REAL*4   (fltarr    in IDL)

Fossil fuel scale factor data was originally computed from emissions 
inventories by Martin Schultz.  Andrew Fusco and Bob Yantosca periodically
update the scale factor data to take into account more recent emissions
inventory releases.

The current emissions inventory data file is located at:

     ~bmy/archive/data/scalefoss_200202/pro/nation96.ems
	
and you need to run the IDL code:

     ~bmy/archive/data/scalefoss_200202/pro/scaleemis_new.pro

to convert the data into the 0.5 x 0.5 binary files for each year,
such as these:

     ~bmy/archive/data/scalefoss_200202/05x05_gen/scalefoss.liq.05x05.1985
     ~bmy/archive/data/scalefoss_200202/05x05_gen/scalefoss.liq.05x05.1986

These 0.5 x 0.5 data files were regridded to 1 x 1 resolution by the
FORTRAN code:

     ~bmy/archive/data/scalefoss_200202/2x25_geos/mk2x25_FOSS_CTMII_GRID.f


and to 4 x 5 resolution by the FORTRAN code:

     ~bmy/archive/data/scalefoss_200202/4x5_geos/mk4x5_FOSS_CTMII_GRID.f
	

Notes:
------
(1) The "scalefoss.tot.*" files are read into GEOS-CHEM by routine
    "read_totco2" of F90 module "geia_mod.f"

(2) The "scalefoss.liq.*" files are read into GEOS-CHEM by routine
    "read_liqco2" of F90 module "geia_mod.f"

(3) Andrew Fusco (acf@io.harvard.edu) recently added data for 1997, 1998,
    in addition to the previous data from 1985-1996.
