Files:
------
isopemis.table        : baseline ISOPRENE emission for each Olson landtype 
	                [atoms C/cm2 leaf/s]

light.table           : Polynomial coefficients for ISOP light correction

monotemis.table       : baseline MONOTERPENE emission for each Olson landtype
	                prior to GEOS-CHEM v. 4.13 [atoms C/cm2 leaf/s]

monotemis.v4-13.table : baseline MONOTERPENE emission for each Olson landtype
	                for GEOS-CHEM v. 4.13 and higher [atoms C/cm2 leaf/s]
	
All files are ASCII format.


Source:
-------
The files isopemis.table and light.table come from the original biogenic 
emissions code (used in the old GISS-II model) from Yuhang Wang.
 
The files monotemis*.table are based on more recent work done by 
Brendan Field (bdf@io.harvard.edu).  


Notes:
------
(1) isopemis.table        is read into GEOS-CHEM by routine "rdisopt.f"
    light.table           is read into GEOS-CHEM by routine "rdlight.f"
    monotemis.v4-13.table is read into GEOS-CHEM by routine "emmonot.f"
    monotemis.table       is read into GEOS-CHEM by routine "emmonot.f"

(2) Monoterpene emissions for some landtypes were revised starting with
    GEOS-CHEM version 4.13; hence the two files.  If you are using version
    4.13 or higher you should use "monotemis.v4-13.table".
