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

This directory includes a netCDF file gc_layers.nc, which contains scale
factors for vertically distributing anthropogenic emissions. The original
scale factor values were provided by Barron Henderson (bhenderson.com, see
email below) as CSV files (also included in this directory). The script used
to generate the netCDF file is vert_alloc.py. For now, the netCDF file contains
scale factors for the energy, industry, and ship emissions sectors, but may
be expanded to other sectors as needed.


Original email from Barron Henderson (4/12/21):
===============================================================================

Attached are two spreadsheets that have all the fractions. The first
[hemi_cmaq_layers.csv] are the vertical allocations for the hemispheric grid.
The second [gc_layers.csv] has been converted to GEOS-Chem layers. For each,
there are really several categories of allocation:

1. g_* are the sectors used to allocate HTAP-EDGAR v2. These might be most
   appropriate for GEOS-Chem, since the specificity will more closely match
   CEDS.
2. The *fire* sectors can be removed since GEOS-Chem will not be using this
   allocation for them.
3. The g_air* will probably also be ignored unless these are being used from
   CEDS.
4. The cmv_c3 are for ships, and will probably be useful.

Overall, that boils down to g_energy for power sector, g_industry for
non-solvent industrial sources, and cmv_c3 for global shipping.
