wrf-chem emissions

Hi, I am working with WRF-Chem v4.6.1 using the MOZMEM chemical mechanism and have set emiss_opt ==10 to read point source emissions. I have a point source emission inventory that includes both CH4 (methane) and benzene. The model correctly reads e_benzene emission and generate benzene output...

Hi, I hope you are doing well. My name is Samira. I am trying to run WRF-Chem in two different months, but continuously. I will be appreciate if you can help me I have one question about running WRF-Chem from 25 January to 10 February (for example, the year 2022, which involves two months) in...

Hi everyone, I'm running into a persistent error when executing ./wrf.exe for a WRF-Chem simulation. The model crashes at the beginning of the run with the following error message: forrtl: severe (66): output statement overflows record, unit -5, file Internal List-Directed Write. From the log...

I have successfully ran wrf-chem using below namelist file. I got wrfout file for time period which i took. But while potting I am unable to see variables like PM2.5, PM10, SOx, NOx, NMVOC, NH3, CO. For my study I want to show a comarison between wrf output and observed value for these...

Hi Everyone I am working with Co2 anthropogeinc edgar dataset by using prep-chem source utility. My issue is that all commands has been successfully executed and after that when i see my wrfout file (by ncview command) then it shows meterological dataset but not showing co2, ch4 etc dataset I...

When I use the RADM2 wrfchemi, I choose the chem_opt=10 emiss_inpt_opt=101 and emiss_opt=4, the WRFv4.5.2 programme runs for some time and then ends the process, I check the rsl file and it just shows the segmentation error, here is my namelist.input, I hope you can give me some guidance! The...

Hi Everyone I downloaded data from this url(https://gml.noaa.gov/aftp/products/carbontracker/co2/CT2022/molefractions/co2_total/) after that when i am trying to regridding it via cdo command, it giving me an error. Cdo command cdo remapbil,gridfile.txt CT2022_2020-03-01.nc co2_regridded.nc...

Hi all. I'm using PRE-CHEM-SRC to generate file for WRF following the exercise2(NOAA - Global Systems Laboratory). Unfortunately the convert_emiss can't run well. So I had to write my own Python program to convert the .bin file generated by PRE-CHEM-SRC into the .nc format. However, when I...

Hi everyone, I'm using convert_emiss to conduct volcanic ash simulation following excercise 2(NOAA - Global Systems Laboratory) I have get the files(wrf_gocart_backg, emissopt3_d01, emissfire_d01, volcs_d01), and when I copy them to convert_emiss directory then run ./convert_emiss.exe, the error...

Hi dears I am trying run anthro_emis< sami.inp to produce wrfchemi files and I brought my inp file to run the "anthro_emis.exe". but it only produce wrfchemi_00::00:00 file until the end of date which is in sami.inp.(stop_output_time = '2022-03-02_00:00:00) and it is stopped. what shall I do...

Hello everyone. I'm trying to simulate the eruption of Changbai Mountain(Baekdu Mountain) following the WRF-Chem 3.9.1.1 Emissions Guide .(https://ruc.noaa.gov/wrf/wrf-chem/Emission_guide.pdf). But It always failed when I runed the convert_emiss program because memory corruption following is my...

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...
