Technical Report No. 25: The WRF Greenhouse Gas Model
6. /chem/module− vertmx− wrf.F
Since WRF version V3.2 all changes that had been made in previous versions in that
routine have already been included into the official WRF-Chem release.
7. /chem/dry− dep− driver.F
The Wesely dry deposition mechanism is excluded by adding the line
config− flags%chem− opt / = GHG− TRACER (line 176)
There are some additional notes without changes in the code in that routine.
<Registry> directory
1. /Registry/registry.ghg
Copy that file from the current WRF-GHG version to the <Registry> folder of the
new WRF-GHG version.
2. /Registry/Registry.EM− CHEM
Add the following line into the Registry.EM− CHEM file to include the registry
.ghg in the actual registry that is used for building the code (line 444):
include registry.ghg
3. Registry/registry.dimspec
In this file, all the dimensions used in the WRF model are defined. For the VPRM
parameters, the number of simulation hours and namelist parameters of additional
variables have to be defined in the following way (lines 75-77):
dimspec
dimspec
dimspec
0 2 namelist=vprm− class
1 2 namelist=run− hours
1 2 namelist=wetland− type
z VPRM− vegetation− classes
z Simulations− hours
z wetland− type
<run> directory
Create the folders <CO2− input> and <CH4− input> in the <run> directory and copy the
*.txt files from both folders of the current WRF-GHG model version to the newly established folders. These files contain the information about the parameters of the VPRM
model and the emission fluxes per unit biomass for the termite emissions.
<dyn− em> directory
1. /dyn− em/module− initialize− real.F
Here the calls of the subroutines used to read in the *.txt files containing the VPRM
