I have setup a WRF-Chem run to simulate smoke over California and while I have created all the wrffirechemi files using the FINN data, the simulation stops after it writes the first file with the error: open_aux_u : error opening auxinput5_d01_2020-09-14_06:00:00 for reading. 100 --------------...

Hello everybody, I am running WRFv4.7.0 with LCZ,(setting use_wudapt_lcz = 1)， But the model crashed or was killed halfway through the run. I set a double nest, only one wrfoutd01 file was output, and I read the content and found that the chemical concentration in it is 0, I didn't see a...

Hello. I am just curious so I am posting here because WRF-Model forum seems to have more replies. I am a new member, and I have posted many questions in WRF-CHEM community. But none of them have been replied to. I am not complaining, just curious. Because I have gotten more replies in WRF-MODEL...

Hello WRF-CHEM community, I have been trying to embed satellite aerosol data into WRF for simulating microphysical processes with real data. So far I have learned: 1. Microphysical schemes either have a built in or a prognostic algorithm for calculating CCN. They have default aerosol...

Hello everyone, I am an MSc student attempting to run WRF-Chem 4.3.3 with indirect effects enabled, in order to investigate the effects of cloud seeding on atmospheric processes. My configuration uses the Morrison 2-Moment microphysics scheme (mp_physics = 10) and RADM2/SORGAM chemistry with...

Dear all, I’m trying to run a WRF-Chem simulation to study the interaction between dust and ozone. My goal is to simulate both dust emissions and ozone chemistry in the same run and analyze their coupling effects. From previous posts, I’ve seen that it might be possible to activate both by...

Today I have downloaded 3 emiss_v03*.F files from ftp://aftp.fsl.noaa.gov/divisions/taq/emissions_data_2005. I have followed the recommended compilation options but got some errors. emiss_v03.F: wrf@wrf-vm:~/wrf/emiss_v03$ gfortran -ffree-form -fconvert=big-endian emiss_v03.F...

I am using chem_opt=202 MOZART-MOSAIC-aq and using mozbc to write in chemical boundary and initial conditions from CAM-Chem. I had a couple of successful runs before: 1) chem_opt = 201 + bc + ic 2) chem_opt = 202 + ic; However, chem_opt = 202 + bc + ic always failed with varying error messages...

Hello, I am trying to update my WRF-Chem version from 3.9.1 to 4.6.0. I am using the same namelist settings. My met_em files were created with WPS 4.6.0. For emissions: Biogenic emissions were generated using bio_emiss to produce the wrfbiochemi files. Anthropogenic emissions are...

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 ...

Hello everyone, I am running WRF-Chem v3.9.1, and my model runs successfully for my selected periods. However, when I try to restart the model using wrfrst_d0... files, I encounter an issue. If the restart time is 00 UTC or 12 UTC, the model reads the wrfrst files correctly and produces...

Hello everyone, I am running WRF-Chem with the RACM-MADE/VBS mechanism for January 2024. I have two domains: East Asia at 27 km resolution and South Korea at 9 km resolution. When I open one of the wrfout files (for example, 2024-01-01_01:00:00), ncview does not show PM10 or PM2.5 variables...

Similar to this error with 4.7.1: Unable to compile WRF-Chem V4.7.1 WRF CHEM with KPP fails to build with ./configure and compile using intel llvm dmpar (option 78) Prior to WRF 4.7.0 and 4.7.1 version 4.6.1 worked without a change. My guess something changed in one of these two versions to...

Good afternoon, My lab mates and I have shifted to the latest version of WRF-Chem, which is 4.7.1. We have been trying to compile this model, but we are all getting the same error. The error message occurs when trying to compile module_phot_tuv. It reads: module_phot_tuv.f90(675): error...

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...

I'm a new user for WRF-Chem. But I found the offical website for WRF-Chem is not available: https://ruc.noaa.gov/wrf/wrf-chem/ Can anyone recommend some tutorials for me? Thanks.

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...

I am a relatively new user of WRF-Chem. I am using the version 3.9.1.1. When running real.exe with wrf_chem_input for a day the program runs, but the wrfinput file produced have zero values for the chemical species. The wrf_chem_input file I am using is actually the last wrfout from the previous...
