    Error in running WRF-Chem Version 3.9.1.1. using MOZART-MOSAIC option (chem_opt=202)

    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...

    WRF-Chem simulation stopped without showing any error in the rsl.error* file

    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...

    Query on the namelist.input file for running WRF-Chem using two domains

    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...

    Abnormally High Precipitation with wrfchem Dust

    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...

    Error in generating chemical lateral boundary conditions

    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...

    On the use of different CBMZ, initial conditions and emissions

    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...

    Grid of emission files not recognized as lat-lon projection, causing a crash

    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...

    Segmentation fault when using nested domains

    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...

    Error in compiling the prep_chem_sources code

    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...

    Links given in the WRF-Chem User's Guide and Emissions Guide are not working

    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...

    WRF-Chem Testing

    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...

    SIGSEGV error related to emissions?

    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...

    Error in running real.exe for simulating dust emissions

    Hello everyone, I am giving 6-hour run (from 06 to 12 hrs) using WRF-Chem for only dust emissions over Indian region on 2 May 2018 by following the instructions given in the tutorial exercise 1 on the official webpage of WRF-Chem (Tutorial Exercises For WRF-Chem Version...

    Halogen chemistry

    We would like to evaluate Br emissions from volcanic activity in Air Quality over Mexico City and also effect of Cl from anthropogenic emissions. Does any one have an update WRF-chem code to do it? Thanks in advance

    How to set chemistry lateral boundary conditions for nested domain?

    Hi everyone, I am a very beginner of WRFCHEM. I am running a three nested domain simulation and I am only interested in the dust concentrations in the inner domain d03. Thus, I chose to set the chem_opt=0,0,401 in the namelist.input file. The construction of initial condition for domain d03 is...

    Problem in the spatial distribution of lightning

    Dear all, I am new in WRF-Chem and are experimenting some problems when using lightning parameterizations with lightning_option = 1 or 2. When I set lightning_option = 1 or 2, I obtain that the spatial distribution of CG_COUNTS and IC_COUNTS has latitudinal or longitudinal cuts, as in the...

    MOZCART creating strange meteorological output

    Hello, I am currently conducting a 2 day, 3-nested simulation over Reunion Island, and I am trying to use the MOZCART mechanism in WRF-Chem (I am using V4.1.2). I previously conducted the same simulation without chemistry, the output of which you can see below with the blue line. However, the...
