wrf-chem emissions

Hi, everybody When I ran WRF-ChemV3.9.1, I found that it reported an error with *** gasodesolver_rodas failure no.1000***， I tried to modify my namelist, such as reducing the integration step size dt and modifying max_dom=1, but I still reported the same error after another hour of simulation...

Dear all, I am running WRF-Chem version 3.9.1 using RADM2-MADE/SORGAM as a chemistry option (chem_opt=2). After getting the successful run, I found the following variables related to organic carbon in the model output: float orgaro1j(Time, bottom_top, south_north, west_east) ...

Dear all, I download bio_emiss preprocessor and its input files for bio_emiss=3 and I can generate my wrfbiochemi_d01 successfully. But I find the input files are quite old (from 2003 and 2001). I search through the forum and google discussion group, I believe many people are using this input...

Hi, guys, I hope I can get your help. At present, I have successfully completed the operation of VPRMpreproc program, and got seven related parameters, such as LSWI, LSWI_max/min, EVI, EVI_max/min and vegetation_fraction_map. But these seven parameters are divided into seven files. So, my...

Dear WRF-Chem officials I want to use WRF-Chem to simulate DMS and its impact on air quality. Although the user manuals do include some information about DMS, I still have many questions. As many articles mentioned, the sources of DMS include 3 main aspects: oceanic, anthropogenic and...

On this webpage https://ruc.noaa.gov/wrf/wrf-chem/tutorialexercises.htm Under exercise 1. There is only one option to download a namelist.input file. However, to run the WPS commands you need a namelist.wps. Did the link get removed by mistake @jordanschnell

Hello, This is a tutorial that will show step by step how to download the WRF-CHEM tutorial data located on the ftp site. Step 1: Open a new terminal window Step 2. Make a new folder called WRF-Chem-Tutorials mkdir WRF-CHEM-Tutorials Step 3. Move to the new folder created in the terminal...

Hi, everybody I use meic2wrf to make wrfchemi, but when I run WRF-ChemV4.5.2, I found that it reports an error Error trying to read metadata, and then it's still running normally after that, but only the information of the weather variable is in the wrfout, and I would like to know what I...

Hello, everyone! I encountered problems when running wrf.exe in WRF-4.4.1. I used anthro_emis to process edgar data and mozbc to optimize chemical boundary. I successfully ran wrf.exe with a single thread, but it can't work with more than two threads. Attached are the namelist.input and...

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...

Hi, everyone. I am new to WRF-Chem. I am following a tutorial video from youtube and try to run wrfchem with emission data. But I cannot get the result when I am running wrf.exe The attachments are my namelist.input and namelist.wps. I am using ubuntu22.02 in WSL. I have tried to use other...

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...

Dear everyone, I ran WRF-Chem successfully with the RADM2-MADE/SORGAM chemistry option (chem_opt=11) using MOZART4 data to include chemical IC/BC in the wrfbdy and wrfinput files. But the MOZART4 data is not available after January 21, 2018. So, to simulate the recent periods, I have to use the...

Dear reader, For my MSc thesis i'm using WRF to model the emission and transport of dust polluted with microplastics. I'm using the AFWA dust emission scheme and the GOCART dust transportation scheme. Due to the microplastics having a different shape, size and density when compared to the dust...

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...

i wonder why this happens ?how can i solve this problems? namelist.input is below. thank you very much!

Hi everyone, I want to perform WRF-Chem simulations with MOSAIC options to study aerosol mass and number concentrations in each bin. The wrfout** file does not contain any aerosol concentration variables. I am wondering if there is errors in the namelist settings (namelist.input) and...

Dear All I am trying to understand the variables used for biomass emissions. In chem/emissions_driver.F, we have the following lines 1. What does 'pcg' stand for? 2. Is it correct that '_b_' and '_f_' are for biomass and fossil, and '_c_' and '_o_' are for C and O components, respectively...

We have a few positions at IIT Bombay that we seek to fill quite urgently under a newly funded project (PAVITRA—Air Pollution Management and Intervention Tool for India). Please see the job profile, and interested candidates may kindly apply through the below link: 1. Project Research...

Hi everyone, My current research efforts concern the study of nitrate levels in Antarctica by WRF-Chem 4.4.2. (chem_opt = 202). Nevertheless, the current modeling results are significantly lower than our observed data. It is possible that the discrepancy is caused by the emission inventory used...
