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...

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...
