wrf-chem

Dear scientist, 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...

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...

I'm only interested in getting the KPP files to compile for a specific WRF mechanism. I don't have a preference for the version of WRF, but I'm using 4.5. I'm compiling on Derecho, but ultimately, I want to set up a Dockerfile to compile the KPP files for different mechanisms since that's all I...

I hope to use the wrf-chem4.4 model to simulate the distribution of co2 and input anthropogenic emissions, but the distribution of co2 is not found in the results. Please help me.The relevant files are in the files archive. the error part is follow Timing for Writing...

When I run wrf.exe it says NO PARAMETER TABLE IS INCLUDED FOR THIS VPRM TABLE OPTION! Here is my error.log and namelist.input. I didn't find the VPRM TABLE in chemics_init.F either. If anyone can respond, I can't thank you enough.

Hi everyone I am working with co2 green house gases. I successfully ran mozbc tool for creating wrfinput_d01 and wrfbdy_d01 and also added anthropogenic activities by creating wrfchemi_d01 file now issue is that i did not find CO2_BCK parameter in my processed file. i set up the chem_opt = 301...

I have a problem, I am running the version wr-chem v4.4, my domain is set to three, but there is such a problem when running, anyone know how to solve it? Appreciate very much The questions are as follows: d01 2010-01-02_00:00:00 wrf: SUCCESS COMPLETE WRF corrupted size vs. prev_size Program...

Hello, I understand how to run WRF-Chem with/without aerosol direct&indirect effects. But to run the model without the chemistry impacts on the meteorology, do I only need to turn off aer_ra_feedback in &chem? Is there any other settings needed to be changed? Thanks, Suqian

When I export WRF_CHEM=1, compiling wrf reports the following error. For details, you can see the compilation log I uploaded (compile_fire.log). module_mosaic_addemiss.f90(2029): error #7002: Error in opening the compiled module file. check INCLUDE paths. [GOCART_DUST] make[2]...

Hi, I've been trying to figure out how to make some sea salt simulations over the colombian caribbean, but I have came across so many problems with the namelist.input. I have not been able to find a clear documentation about the chemistry module of WRF and even less about sea salt modelling with...

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...

I'm running WRF452 on the Linux subsystem of my own Windows 11 system in my pc to simulate a typhoon. When I use ONE processor, wrf.exe runs successfully but slowly. However, when I use 16 processors for fast running speed, wrf.exe runs several hours and output 4 hours wrf_out* data, then it...

Hello all, I'm trying to compile WRF v4.6.1. I noticed that for version 4.6 and 4.6.1 there are configure_new and compile_new along with configure and compile. While for older versions, they only have configure and compile. I'm wondering what are the differences between configure and...

Hello, I'd like to draw geopotential height at 850 hPa for WRF-Chem output via NCL. I have variables as below. PH(Time, bottom_top_stag, south_north, west_east): perturbation geopotential [m2 s-2] PHB(Time, bottom_top_stag, south_north, west_east): base-state geopotential [m2 s-2] P(Time...

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...

Hello, I just wonder what does bdy_width mean in wrfbdy_d01 file. In my wrfbdy_d01 file, bdy_width = 5. float no2_BXS(Time, bdy_width, bottom_top, south_north) ; no2_BXS:FieldType = 104 ; no2_BXS:MemoryOrder = "XSZ" ; no2_BXS:description = "NO2 mixing ratio" ; no2_BXS:units = "ppmv" ...

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...

Hello, Is there a way to use MOSAIC with dust emissions in the WRF-Chem model? MOSAIC has 4 dust bins, while dust_opt uses 5 bins. I saw this post from a few years ago Problem running CBMZ-MOSAIC (4 bins) with AFWA dust scheme and was wondering if a solution was found. Thanks, Alexander

Hello, I am wondering if there are any processes would change chem array (e.g. gas) outside of chem (chem_driver)? I have checked the dyn_em and PBL, shallow cumulus won`t change chem in my case. But i am not very familiar with the other processes beyond chem_driver such as "chem_adv_tim" and...
