Dicarbonyls simulation

Overview

As an option in GEOS-Chem, you can run with more tracers to study the dicarbonyls chemistry.

NOTE: The files needed to use the KPP solver were not generated for the dicarbonyls chemistry. You can not run the dicarbonyls chemistry with the KPP solver. You have to use SMVGEAR.

Input files

For this simulation, you need different input files for the chemistry:

• globchem.dat
• jv_spec.dat
• ratj.d

You will also need a restart file with additional tracers. You can create your own (see GAMAP manual) or download one from the ftp:

 ftp ftp.as.harvard.edu
 cd pub/geos-chem/public_releases/
 get GEOS-Chem.v8-02-01-public-dicarb.rundir.4x5.tar.gz

or

 get GEOS-Chem.v8-02-01-public-dicarb.rundir.2x25.tar.gz

You'll also need a specific restart file for the SOA tracers. You can find one in the same archive file on the ftp.
