WRF-Chem help with MOZART

[Guido Conto Echeverria]

Hi everyone,

I am implementing the model (WRF-Chem V3.8.1) and it has been a real challenge, the reason why I am writing to you today is because I have encountered a problem with MOZART. I give you a brief explanation:

1- Compile and execute the WRF model
2- Couple the Chem module
3- Configure namelist.input
4- Use Prep-chem-src for anthropogenic emissions (requires convert_emiss.exe)
5- Use MEGAN (wrfbiochemi_d01)

When trying to use MOZART and follow the following methodology:

1. Set chem_opt =0 to run real.exe and use wfinput* and wrfbdy* files to prepare your emissions like anthropogenic emissions, biogenic emissions and biomass burning emissions;
2. Set chem_opt=112 and run real.exe
3. Use mozbc to modify wrfinput* and wrfbody* files;
4. Use ncview to check these files.
5. Run wrf.exe

I find a segmentation fault (core dump) when I run ./real.exe with chem_opt == 112.

I attached namelist.inpunt, rsl.error and rsl.out.

The objective of using mozart is to determine the photolysis coefficients, if they know a configuration to be able to determine them, it would be very useful as well.

I would greatly appreciate some help

Regards

Guido

Guido,

I am very confused by your nameslist. When you run with MOZART chemistry, there is no need to have a wrfchemi_gocart_bg_d<domain> file. It seems you are mixing a few things

​here

. Please see the WRF-Chem User's Guide or look at some of the WRF-Chem tutorial examples

​ for more information.

Dear,

Gabriela

Thanks for your answer.

My namenlist.input, I filled it with the online WRF-Chem tutorial
(https://ruc.noaa.gov/wrf/wrf-chem/SA_tutorialexercises.htm), that's why you have all the options that correspond to active PREP-CHEM-SRC.

The problem is when I try with all options to run real.exe with chem_opt == 112.

as I said, you are mixing various setting. When you run with MOZART chemistry you do not need a GOCART background file.  I am not familiar with  PREP-CHEM-SRC but I believe it does not gives you emission output on MOZART speciation. 

To run with MOZART, please see our Website and the provided User Guides for more information (https://www2.acom.ucar.edu/wrf-chem). We provide tools to create IC and BC, fire emissions and input for MEGAN biogenic emissions. We also provide a tool that allows you to use global emission inventories. 

I attach an example MOZCART namelist file.
