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

The ICOADS ship inventory was first introduced in GEOS-Chem v8-02-03. 
It contains the species NOx, CO, and SO2. 

Chulkyu Lee worked on implementing ICOADS into GEOS-Chem.
The source code is in file icoads_ship_mod.f.

                           Units are kg CO/month


NOX_MM.geos.1x1         -- Monthly ship emissions for NOx (MM = 01...12)
                           Units are kg NOx/month
