Files:
-------------------------------------------------------------------------------

(1) FracNOx_binary_5hrs_20gs.dat:

      File contaning the fraction of NOx remaining for  
      ship emissions [unitless]

(2) IntOPE_binary_5hrs_20gs.dat:
  
      File containing integrated Ozone Production Efficiency for 
      ship emissions [molec O3 produced / molec NOx lost]

NOTE: These files are in flat binary format (NOT bpch format!).  We may 
try to convert these to netCDF at a later date.

Dear GEOS-Chem support team,

Past GEOS-Chem user's meeting I had a presentation about accounting for 
non-linear chemistry of ship plumes in the GEOS-Chem model. Recently I got 
an email from Melissa asking about the status of my update. I think my code 
is ready to be incorporated in the GEOS-Chem model. I'm not sure what the 
standard approach for this is, I've created a patch file between my standard 
model v8-03-02 and the version with the new ship emissions approach. I've 
attached an Appendix from a report I wrote a year ago, which contains some 
more information about how the method is programmed. 

I'm aware that some routines might need to be moved to new files (e.g. the 
interpolation of the Look-Up-Table is now done in icoads_ship_mod.f), please 
let me know if you need any help with this. 

Also please let me know if you need any other source files. 

I've also attached the look-up-tables.

The reference for my work has been published today:

Kind regards,
