* We have prepared 1x1 (this means  1 degree by 1 degree) distributions 
  for three types of biomass burning in the developing world:

   woodfuels burning (including both fuelwood and charcoal burning),
   residue and dung used as biofuels, 
   burning of residues in the fields.  

* All three of these files contain amount of biomass burned per box
  in units of Tg dry matter.

* Sample fortran programming which can be used to read each file is:

  DIMENSION CCMAP(360,180)
  READ(**,1)((CCMAP(I,J),I=1,360),J=1,180)
1 FORMAT(8E10.3)

  The I,J, numbering uses the I-index to move east to west around the globe
   starting with its I = 1 box bordering (left edge) on the international
   date line.  The J ordering starts with the J = 1 box bottom edge on the
   South Pole and moves north.
  (The files were created in 1P8E10.3 format.)


* The woodfuels file is called WDF.1x1 and total of all 1x1 boxes is 1323.17 Tg.
* The residue/dung biofuels file is CMB.1x1 and total is              732.82 Tg.
* The burning-in-fields file   is BIF.1x1 and totals                  406.36 Tg.


* The derivation of these distributions is discussed in the paper by Yevich
and Logan, 2003.  If you use any of these files, please cite the following:
