Overview:
==============================================================================

The data was prepared by Nick Simone and converted to netCDF file 
format by Sebastian David Eastham.

Christoph Keller (ckeller@seas.harvard.edu) further converted the netCDF 
file for compatibility with HEMCO.


Files:
==============================================================================


(1) AEIC.nc

 -- Contains arrays fuelBurn, NOx, HC and CO (360,180,49), which is 
    placed on the GENERIC GRID at 1x1 degree resolution and resolved
    vertically in 60.96 m increments for the first 304.8 m, and then
    304.8 m increments thenceforth. The data is based on the Aircraft
    Emissions Inventory Code (AEIC), based on 2005 scheduling data.
    There are 12 files, with X corresponding to the month of the year.

       -- Sebastian David Eastham (seastham@mit.edu)


(2) aeic_vertregrid.py

 -- Python script that you can use to vertically regrid the AEIC.nc file
    to other vertical resolutions (e.g. GEOS-Chem, GCAP, etc.)


(3) AEIC.47L.gen.1x1.nc

 -- These are the AEIC emissions remapped onto GEOS-Chem levels. 
    Script aeic_vertregrid.py was used to remap the original data
    onto the GEOS-Chem grid and to convert units from kg/s to kg/m2/s.
