Files stored in /as/group/geos/data/GEOS_2x2.5/CH4_201203:

   (1 ) resident.2x25.2004.bpch         : Methane emission from biofuel burning

   (2 ) gmi.ch4loss.geos5_47L.2x25.bpch :
          CH4 loss frequencies. These values constitute a linearized
          stratospheric CH4 chemistry scheme. Loss freq. from 4x5 degree
          output from the GMI model. Values are for "generic" year 1985.
          Units are [1/s]. (Courtesy of Lee Murray)


Files stored in /as/group/geos/data/GEOS_2x2.5/CH4_201203/wetlands:

   (1 ) Carbon_litter.2x25.bpch         :  Carbon emission from litter
   (2 ) Carbon_soil.2x25.bpch           :  Carbon emission from soil
   (3 ) TSKIN.geos5.2x25.YYYY.bpch      :  Monthly and annual mean skin temp
                                           for GEOS-5 for the year YYYY
   (4 ) Wetfrac.2x25.bpch               :  Wet fraction in each grid cell


Files stored in /as/group/geos/data/GEOS_2x2.5/CH4_201203/GWETTOP:

   (1 ) GWETTOP.geos5.2x25.YYYY.bpch    :  Monthly and annual mean soil wetness
                                          for GEOS-5 for the year YYYY
 

	The program used to create TSKIN and GWETTOP is
		/home/kjw/emissions/wetlands/IDL/annual_met.pro
	Carbon_litter, Carbon_soil, and Wet_frac were sent to me by
		Jerome Drevet.  I did not receive the program that created them
	Wet_frac follows a wetlands map created by Jed Kaplan.
		The map is described by Bergamaschi et. al. 2007
	Carbon_liter and Carbon_soil are output from a 20th century run of
		the Lund-Potsdam-Jena Dynamic Global Vegetation Model.
		They were created by Jed Kaplan and sent to me by Jerome Drevet

	
Emissions were collated by Kevin Wecht (kjw@seas.harvard.edu).
Data are stored in binary punch file format and have units  [molec CH4/cm2/s].
