Dust flux tuning in WRF-Chem GOCART

[jztindan]

I'm trying to tune dust flux in the original WRF-Chem GOCART module by changing the current tuning constant (C=0.8D-9) in chem/chemics_init.F. I'm using option 300 (GOCART simple aerosol scheme, no ozone chemistry) and dust_opt=1 (GOCART). After performing simulations with different constants i.e., 0.2D-9, 0.5D-9, and 0.8D-9, all of these constants in terms of the dust amount (both in concentration and vertically integrated) look similar. What is the best way to properly tuned these constants? I appreciate the help.

Since you haven't gotten a response @jztindan let me suggest some google groups that focus on WRF chem

wrf-chem-mozbc - Google Groups

groups.google.com

wrf-chem - Google Groups

They might be able to help you

Thanks @William.Hatheway. I figured it out. Changing ch_dust in phys/module_dust_emis.F works for me.

@jztindan glad you were able to figure it out.

Hello, I am also simulating dust transport. I have set up two nested domains, but when running WRF-Chem, various errors keep popping up. I'm unsure how to modify the namelist.input file to resolve these issues. The attachment below is my namelist file, thank you very much。

Please open a new thread as the issue is different.

Thank you for your reply. My WRF-Chem model has now begun running. I've realized that in the namelist.input, under the &physics section, certain parameters need to be written only once, rather than twice. For example, it should be num_soil_layers = 4，instead of num_soil_layers = 4， 4，
