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...

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...

Hi, I'm new in WRF-Chem, so I am trying to run the tutorial examples. However, I cannot access the data pointed out in the following FTP link https://ruc.noaa.gov/wrf/wrf-chem/tutorialexercises/tutorialexercises001.html I try to connect to the server on a Mac computer using the finder: *...

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...

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.

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...

Hi everyone, When I tried to compile WRF-Chem with the .bashrc setting of WRF_CHEM=1, WRF_EM_CORE=1, WRF_KPP=1, WRF_NMM_CORE=0, the following errors were recorded in the compile.log file. Also, some other fatal errors occurred. The compile.log file and .bashrc file are attached. Could...

When I tried to compile WRF-Chem V3.9.1 with WRF_KPP=1, WRF_CHEM=1, WRF_EM_CORE=1, the following errors were recorded in compile.log. procedure(xsqy), nopass, pointer :: xsqy_sub 1 Error: Fortran 2003: Procedure components at (1) are not yet implemented in gfortran...

Hi! I'm a new user of WRF-Chem and I was trying to do exercise 1 of the WRF-Chem tutorial (https://ruc.noaa.gov/wrf/wrf-chem/tutorialexercises/tutorialexercises001.html) but I cannot access to the data needed to run the exercise. Am I the only one with that problem? The namelist is perfectly...

EDIT: This bug has been addressed in v4.4.1 Dear WRF-Chem Users, It has come to our attention that there is a bug in v4.4 that prevents users from compiling the model. To remedy this, users will need to modify the following file: WRF/chem/depend.chem by changing the line (L232) FROM...
