wrfchemi_d01 emissions every one hour can not get done correctly

[Claudio Porrini]

Hello everyone,

I am looking for some help.

I have created with prep_chem an emtpy file (with zeros in all the field emissions variables).

At the moment I am testing the model and the input.

Created wrfinput with chem_op = 0 and then with after linking my binary file from the ouput of prem_chem.exe I used convert_emiss.exe to generate wrfchemi_d01.

wrfchemi_d01 I modified with emissions I am creating from satellite data copernicus.

My problem it is that I can read the wrfchemi_d01_<date> but just for the firs hour, and this i can see it in the visualization of the wrfout*.

I tried many ways of techniques (from forum and documentation) to put emission every hour in the wrf chem simulation.

At the moment, I can run the model with the wrfchemi_d01_<date> dimensions 1 time x 1 level x lat x lon, and what I have done was creating extra time levels copying the emissions from the first hour.

My final wrchemi_d01_<date> dimensions is 48 time x 1 level x lat x lon

wrf.exe executes with no problems and seems that the data is introduced but when I a compare between a sample simulation with only the first hour with emissions and another simulation with 48 emissions, the solutions seems the same, only wrfchem cachts my first time emissions.

Then I have tried to create one wrchemi_d01_<date> for every hour, and I get the same results.

Then I have tried wiht io_style_emissions = 1 and change and create 2 files wrfchemi_00z_d01 and wrfchemi_12z_d01 with 12 frames each file.
Same results for a 24 hour run simulations.

I wil try with the restart option but ideally i would prefer get this data through the options describes before.

I attached my namelist.input.

Hope someone can help me, really appreciate.
Cheers from Uruguay.

Claudio.

Hi Claudio

I am not fully following what you are trying to do and what does not work or work. We cannot help with prep_chem_sources and neither with chem_opt 301. For this you will please have to contact the main user forum: https://forum.mmm.ucar.edu/

I suggest adding the emission fields to your output which will tell you what is read in and what not.
