Hi all, new WRF-Chem user and first time poster. My three day, four nested domain simulation runs for the first 24 h (2023-02-22), then fails to move onto the next day, with the following error. ERROR: Could not find matching time in input file wrfchemi_d01_2023-02-22_00:00:00 It should...

Hello all, I am using FINNv2.5 for a biomass burning simulation with WRF-Chem v 4.4.1 using MOZCART. I have attached my namelist and rsl file. However, I am running into a segmentation fault that I do not understand how to fix. Any help would be greatly appreciated. Below is part of the error...

Hello, Everyone. I am using AWS(ec2-user) (WRFv4.2_dmpar) as a platform of WRF, I found it on WRF official website (Cloud WRF), I am not able to locate convert_emiss.exe, all I saw was convert_emiss.F, Kindly guide.

Hello everyone, I want to perform WRF-Chem simulations using the CBMZ-MOSAIC chemistry option to study aerosol-cloud interaction. I want to use anthropogenic emissions from the EDGARv5_MOZART_dataset (from the EDGAR v5.0 emissions inventory speciated for the MOZART chemical mechanism) or...

Hello everyone , I am giving a test run with two domains (d01:20 km and d02:4 km) with one-way nesting by setting 'feedback' option to '0' for just 2 days. The WRF-Chem ran successfully when I used the MOZCART option (chem_opt=112) and MOSART-MOSAIC (chem_opt=201). But, some specific errors only...

Hello Been trying to resolve this error issue by looking for answers somewhere else in the internet, but to no avail. I am running WRF-Chem with anthropogenic emissions from EDGAR-HTAP and bio emissions from MEGAN, all the tools necessary before running WRF-CHEM, such as anthro_emis...

Dear all, I have some small queries about the setup of some variables in 'namelist.input' file for running WRF-Chem to study aerosol-cloud-climate interaction. 1. After going through various research papers on aerosol-cloud interaction studies using the WRF-Chem model, the user guides, and...

When I using WRF-Chem with the version 4.4.2 on Cheyenne, the model quits at the first time step. 224 cpu are used and the debug_level is 500. CBMZ and MOSAOC are used and the detailed information is in the namelist. I have compressed some of the rsl.* files with "Error" and namelist.input into...

Dear all, I am running WRF-Chem Version 3.9.1.1 on a Linux server with 32 processors (RAM: 378 GB) and the gfortran compiler. I used the EDGARV5 MOZART dataset for generating anthropogenic emission input files ('wrfchemi_d<domain>_<date>.nc'), FINN Version 1.5 dataset for generating fire...

Hello everyone, I was able to run real.exe successfully, and then I was also able to make the chemistry input files that are needed to run wrf.exe. Then I gave the following command: mpirun -np 28 ./wrf.exe >& wrfrun.log &. At first, the simulation went on for some time, but then it stopped...

Dear all, I have gone through the WRF-Chem User's Guide and I have some queries on the namelist.input file before running wrf.exe. 1. 'Kemit' is either 1 or 8 on the sample name list in the tutorials provided on the WRF-Chem official website. I am using the EDGARv5_MOZART_dataset (from EDGAR...

So this here's a strange one. A while back my advisor and I ran a 3-domain simulation centered on Puerto Rico where we used wrfchem to add dust for the SAL. We've only now gotten around to analyzing the results and it's given some odd precipitation quantities. The no-dust (no wrfchem) run...

Dear Sir/Madam, I have gone through the 'WRF-Chem 3.9.1.1 Emissions Guide'. Now, I am using mozbc to generate chemical lateral boundary conditions for WRF-Chem simulations (as described on page 38 of the emission guide). For that, I am using the MOZART-MOSAIC_4BINS input provided in the document...

Hi all, I am a new user of WRF-Chem and have several questions related with CBMZ and initialization of the simulation: 1) Can I use prep_chem and/or the programs provided by NCAR to prepare the emissions (bio, anthro) when using the CBMZ chem_opt? 2) Can I use the software mozbc to initialize...

Dear WRF community, For my MSc thesis research I am running WRF-CHEM with emission files I had to create myself. These emission files have the following naming convention: <wrfchemi_d01_yyyy-mm-dd_HH:MM:SS>. This particular WRF-CHEM simulation covers 24-06-2018 up to 01-01-2018, thus running for...

Hello everyone, I'm trying to run WRF-CHEM with all the chemistry options turned off, just to test that it works as expected. The idea is to add biogenic emissions later when we check that everything is ok. The first test simulation without nesting worked fine. However, WRF-CHEM raises a...

Hello everyone, I want to set up the executable file for PREP-CHEM-SRC (prep_chem_sources_RADM_WRF_FIM.exe) to prepare the chemistry input files for running WRF-Chem. For that, I have downloaded the tar.gz file 'prep_chem_sources_v1.5_24aug2015.tar.gz' from the WRF-Chem ftp site...

Hello everyone, I have successfully completed the tutorial exercise for dust-only simulations. Now, I am learning how to use the global emission data sets to make the emissions input file. But I learned that many of the links provided in the WRF-Chem User's Guide and WRF-Chem Emissions Guide are...

Hello, I am a sys admin for my university's HPC and I have been tasked with installing WRF and WRF-Chem on our machine. Needless to say I am not familiar with using the software/model to do actual work, just the installation procedure. I have successfully compiled both and I have moved on to...

Hi everyone! I was running WRF-Chem3.9.1 with KPP, reinitialized the meteorology every 24 hours but with chemistry field from previous time step when doing re-initialization. After running several days, a SIGSEGV occurred (see all_rsl.error.txt attached). Since I found in the error log file...
