    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...

    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...

    Strange chemical species distribution in output MOZART MOSAIC

    Hello, I am trying to run WRF-Chem with MOZART MOSAIC for Reunion Island, off the coast of Madagascar. I am using WRF-Chem V4.1.2 with KPP. I am using CAMS and CAM-Chem for the initial and boundary conditions, which look okay. However, some species (namely CO) has a very strange distribution in...

    WRFDA & WRFPLUS in WRFCHEM

    Good morning, So I saw this in the release notes for 4.4.1 Just so I understand correctly, this means that WRFDA and WRFPLUS functionality are now enabled for WRF-CHEM? I want to include them in my scripts but I don't want to add them if they are not truly functional.

    Using dust only opt, no Dust_x variables in wrfinput_d0x files

    I am a very beginner of the WRF modle. I am using WRF-Chem (WRF version 4.4.1) with chem-opt=401 and dust-opt=1 to conduct the exercise 1(dust only simulation) on the WRF-CHEM homepage. But after I run the real.exe program, there is no Dust_x variables in the wrfinput files. Is there any way to...
