Hello,
We are trying to run WRF-CHEM simulations using CMIP6 data from future predictions. We were wondering if there is any way to include fire emission ( future fire emission) data in our runs.
Thank you very much in advance,
Polyvios
Hi,
I am trying to add in new chemicals into WRF-Chem. To do this, I
Copied and renamed a chemical mechanism from the KPP (in my case, it was RADM2_KPP)
I renamed the files inside my new chemical mechanism to reflect the new name
I adjusted the chemical equation file to reflect the chemical...
Dear community,
I have been trying to run WRF CHEM simulation using the single layer UCM (sf_urban_physics = 1), like the title says. However, no matter what I try the simulation stops after some period of time. I have conducted successful simulations using no urban (sf_urban_physics = 0) or...
Hello all,
I want to add atmospheric heating rate as a variable in the WRF output files (i.e., 'wrfout_d0*' files). I have gone through a previous forum conversation (Output the atmospheric heating rate) and after considering the suggestions available in that conversation, I made a iofields file...
Dear all,
I have problems in how to add new reactions in the gas phase in WRF-Chem?
I want to add new reactions in saprc99.eqn. What revisions should I make? Are some revisions made automatically by the KPP methods in WRF-Chem? Could someone with relevant experiences help me with this problem...
Dear all,
I'm using COAWST v3.7 (WRF v4.1) and want to compile WRF-chem and KPP, howerver I have problems in buiding executables. I've successfully ran WRF without chem. Here is the log file, Additionally, here are part of my enviroment settings in bashrc file:
### flex

Merry Christmas to all.
I know the "t_phy" in chem code is the air temperature in the middle of each layer. But I don't know which variable in wrfout file represent it. Is it "T"? Thanks in advance.
Hi all,
I tried to run WRF-Chem with LCZ and urban canopy scheme, but it failed.
The attachments are namelist.input, namelist.wps, and rsl.error.* files.
Please note that:
1. I tried to run WRF-Chem with default land use and it was successful.
2. I tried to run WRF-Chem with LCZ land use...
Hello,
I am using WRF-Chem v3.7.1 to look at the gas concentrations during Mar 2022. The model with chem_opt=132 produced very low NH3 gas concentration whic is obviously wrong. However, the resutls from some other options (e.g. chem_opt=131) makes more sense in terms of the magnitude and...
Dear all,
I am performing WRF-Chem v3.9.1 simulations using the CBMZ-MOSAIC chemistry option (chem_opt=32). My parent domain simulation was completed successfully. But, after using ndown to generate boundary conditions for the nested domain files, I gave a run for the nested domain, and the...
I met a problem when compiling WRF-Chem on Cheyenne.
There are some errors when compiling WRFV3.6.1 with Chem3.5.1. The log file is attached named compile.log.zjm. The other one is configure.wrf. BTW, I have succeeded to compile WRFV4.2 with chemistry before, so I guess it seems like a problem...
Hello,everyone!
I read an article (Importance of reactive halogens in the tropical marine atmosphere: a regional modelling study using WRF-Chem) which used WRF-Chem to model the halogens and said MOZART-4 mechanism has been extended to include bromine, chlorine and iodine chemistry. Then I...
Dear all,
I have been stacked on this problem for half a year, I am gateful that if someone could help me solve this problem.
My situation is that the WRF-Chem V3.9.1.1 is always stopped after photolysis driver (rsl.error.000?) and it also happens in latest version (WRF-Chem V4.5.1).
The stop...
Hello everyone! I just finished compiling wrf-chem and I'd like to know if it provides downloadable input and output examples? Just like wrf-cmaq in this URL: https://www.epa.gov/cmaq/cmaq-inputs-and-test-case-data
Let me test if it works successfully.
In fact, I pay attention to the output of...
Hello,
I am currently engaged in a comprehensive inquiry into the methodology employed by WRF-Chem for SOA (Secondary Organic Aerosol) calculations.
In my current configuration, I have MOSIAC integrated with MOZART, utilizing the chem_opt parameter set to 201, corresponding to...
Dear all,
I have a small query regarding the computation of the perturbation in atmospheric variables due to aerosol-cloud interaction (ACI) using the WRF-Chem model. In the case of aerosol-radiation interaction (ARI), the perturbation in atmospheric parameters can be computed by taking the...
Dear all,
I am running WRF-Chem-3.8.1 with chem_opt=9. I have been running WRF since 0:00 on July 15, 2016. Everything was fine at first, but by 17:00 on July 17, there were no wrfout files generated and everything seemed to be stuck. But I looked at the log file and there was nothing...
after finishing DUST1,there is “ncview wrfinput_d01”,but in my view has not sufficient variable.l really wanna know why?anbody can help me?(sorry,my engish is not good)
thank you very much!
