Files:
------
acetone.geos.2x25    : Contains monthly mean acetone emissions from grasslands,
	                and from biogenic sources, for the TAGGED CO simulation.

ch3oh96.geos.2x25    : Surface concentrations of CH3OH, ISOPRENE, and 
isop96.geos.2x25     :  MONOTERPENES from 1996, supplied by Bryan Duncan.
mono96.geos.2x25     :  

tagco_mask.geos.2x25 : Country mask for ICARTT tagged CO
                        (1=USA/Canada, 2=Mexico, 3=Europe, 4=Asia)

Source:
-------
Acetone emissions data in "acetone.geos.4x5" was taken from a 4 x 5 GEOS-CHEM 
simulation for the year 1994 done by Brendan Field.  The 4 x 5 data were then 
regridded to 2 x 2.5 and 1 x 1 resolution by Bob Yantosca.  

The data in the files "ch3oh96.geos.2x25", "isop96.geos.2x25", and 
"mono96.geos.2x25" were implemented by Bryan Duncan because the GEOS-3 
surface temperatures caused the biogenic emissions of these molecules to 
be too high.  To prevent this error, fields taken from 4 x 5 GEOS-STRAT 
simulations were used. (These were regridded to 2 x 2.5 by Bob Yantosca.)
Bryan Duncan has since abandoned this approach, so these files are not 
used anymore by the standard CO simulation.

The "tagco_mask.geos.2x25" file was created with IDL program 

	~bmy/IDL/regrid/regridh_tagco_mask.pro

The original data file (1 x 1.25 resolution, F77 unformatted binary) was 
provided by Eric Nielsen at GMAO (nielsen@gmao.gsfc.nasa.gov) and is stored 
at this location at Harvard:

	~bmy/archive/data/tagged_CO_200106/1x125_geos/tagco_mask.f77_unf
