Problem reading pm10 data from local wrfchemi_00z_d05 emission data


New member
Dear all,

I am trying to input my own PM10 emissions into WRFchem (v4.4). The model reads the input file without errors, but the emis_anth( :,:,:,p_e_pm_10) remains zero throughout the entire domain. After some time steps, my result is not reflecting my emission.

I have built a wrfchemi_00z_d05 file based on an example I got from a colleague. In order to keep it simple, I am using the following parameters in my namelist (see attached for the rest of the parameters):
chem_opt = 303, 303, 303, 303, 303,
emiss_inpt_opt = 0, 0, 0, 0, 1,
emiss_opt = 0, 0, 0, 0, 2,
(Note that I am emitting in the inner domain only)

In order to follow the process, I am printing inside module_emissions_anthropogenics.F the sum of the emis_anth( :,:,:,p_e_pm_10) array getting a zero value.

Does anyone have any clue why the input values don't reach the anth_emis array?

Thank you very much in advance.
Best wishes,

Hello again.

I have also tried with the following parameters, still with no luck:
chem_opt = 112, 112, 112, 112, 112,
emiss_inpt_opt = 0, 0, 0, 0, 1,
emiss_opt = 0, 0, 0, 0, 8,

Thank you!
