wrf-chem emissions

Hi all! I am interested in using the tracer_opt = 2 in WRF to eventually model the emissions of a custom aerosol. I have been using WRFv4.7.1 with WPSv4.6.0, but have come across the same error in WRFv4.3.3 with WPSv4.3.1, so I don't believe that it is a version issue. I have been able to...

Hello everyone, I am currently running VPRM on the basis of WRF-Chem V3.9.1.At present, I have successfully used pyVPRM to output the variables required for VPRM such as EVI, LSWI, etc., and write the relevant variables to vprm_input_d01. The variable information and dimensions are as follows ...

Dear all, During WRF-Chem simulations, in addition to accounting for wildfire smoke emissions, is wildfire heat flux considered? If not, how can wildfire heat flux input be added? If yes, how can it be disabled? Kind regards,

I'm using WRF version 4.5 with the PREP-CHEM-SRC 1.5 utility to convert daily emission files for a two-day test case (from 2024-03-15 00:00:00 to 2024-03-16 00:00:00), with outputs every 6 hours (matching my met_em files). I run PREP-CHEM-SRC daily and loop over each day to generate 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) ...
