In this folder, are the NEI2005 data processed by Aaron van
Donkelaar. Original gridded data on a 4 km x 4km grid (REAM model)
were provided by Yuhang Wang. Four (4) related masks have been created
by Philippe Le Sager.  Code by Donkelaar and Le Sager to read and
process the data is available in GEO-Chem v8-02-04.


Notes:
Emissions are distributed on 5-levels.
NIT, BC and OC are not used in GC.
