Hello, Is there a way to use MOSAIC with dust emissions in the WRF-Chem model? MOSAIC has 4 dust bins, while dust_opt uses 5 bins. I saw this post from a few years ago Problem running CBMZ-MOSAIC (4 bins) with AFWA dust scheme and was wondering if a solution was found. Thanks, Alexander

Hello, I am wondering if there are any processes would change chem array (e.g. gas) outside of chem (chem_driver)? I have checked the dyn_em and PBL, shallow cumulus won`t change chem in my case. But i am not very familiar with the other processes beyond chem_driver such as "chem_adv_tim" and...

Hi there, I'm running WRF-Chem with MOZART/MOSAIC option (chem_opt=201). The run crashes out at the start time with this error: I didn't find a similar error in the forum. Does anyone know what it is about? WPS and real.exe run with no issues. Also, when I use simpler chemistry options like...

Hi all. I'm using PRE-CHEM-SRC to generate file for WRF following the exercise2(NOAA - Global Systems Laboratory). Unfortunately the convert_emiss can't run well. So I had to write my own Python program to convert the .bin file generated by PRE-CHEM-SRC into the .nc format. However, when I...

Hi everyone, I'm using convert_emiss to conduct volcanic ash simulation following excercise 2(NOAA - Global Systems Laboratory) I have get the files(wrf_gocart_backg, emissopt3_d01, emissfire_d01, volcs_d01), and when I copy them to convert_emiss directory then run ./convert_emiss.exe, the error...

Dear all, I am working to compile WRF and WRF-Chem recently. I have compile WRF and WPS successfully, so I try to do more work to ocmpile wrf-chem. I use the gcc version is ( gcc (GCC) 11.4.1 20231218 (Red Hat 11.4.1-3)) and GNU Fortran (GCC) 11.4.1 20231218 (Red Hat 11.4.1-3). I believe the...

Hello Everyone, I am currently working with WRF-Chem version 3.9.1, using the following inputs: - Meteorological Forcing Data: ERA5 . - Anthropogenic Emissions: EDGAR . - Biogenic Emissions: MEGAN . - Fire Emissions: FINN . - Chemical Boundary Conditions: WACCM/CAM-Chem. I am attaching my...

Hi, I have been troubled by a problem for a long time and I hope to get your help. I am currently running WRF-VPRM, and I have prepared the necessary input data and settings. However, when I extracted the run results from WRFout after running, I found that in the output of VPRM, the EBIO_GEE...

I used to use the meteorological model WRF. Recently, I added the chemical module and recompiled it. However, the wrfout file that should have been output hourly has been output every three days. When the chemical module is turned off, the hourly wrfout file can be output normally. I want to...

hi all, ive been trying to run wrf chem using anthro and bio emiss data, i got program killed while system calculate megan emissions, ********************************************************************* * PROGRAM:WRF-Chem V4.4 MODEL No git found or not a git repository, git...

Dear WRF Community, I am currently using WRF-Chem to simulate dust events. I would like to observe the impact of turning on and off dust radiation feedback on the analysis results while retaining dust emissions. However, I am unsure how to turn off sand and dust radiation feedback. I hope to...

Hello, I would like to read in multiple anthropogenic emission files into wrf-chem without combining them into one file. How should I proceed? I appreciate any help or suggestions. Thanks, Kiarash

this my success progress on build WRFChem Model i attach on txt file, maybe can help you that need to build it also i attach my pdf file, (look at the bottom of the file first about some solution that i use to fix my error compiling)

Hi Everyone, I noticed my WRF-Chem outputs on p25i, p25j, and soila at the first model layer have abnormal concentration pattern. This strip-type pattern only happens at the first layer. Other species do not have this issue. Does anyone know why cause this issue? Here is dyanemic setup in...

Hello everyone. I'm trying to simulate the eruption of Changbai Mountain(Baekdu Mountain) following the WRF-Chem 3.9.1.1 Emissions Guide .(https://ruc.noaa.gov/wrf/wrf-chem/Emission_guide.pdf). But It always failed when I runed the convert_emiss program because memory corruption following is my...

Motivation The reason why I am trying to compile WRF v3.5.1 on Derecho is that I need to work with a modified version of it that includes extensive revisions to the chemistry part and transferring these modifications to later versions of WRF is not practical for me. Also, I will probably further...

Hello everyone, I currently work on running WRF-Chem after Hybrid 3DVar-ETKF WRFDA, and encountered a persistent segmentation fault (wrfchem-run stopped at 'calls rrtmg_lw'). The Hybrid 3DVar-ETKF process contains the following steps: 1.wrf_3dvar_input_*.e001,wrf_3dvar_input_*.e002: Be...

Hi all, I want to output EFFC (Cloud droplet effective radius) to the WRF-Chem output file. These are the steps I followed: 1. Added 'EFFC' in the MP_MORR_TWO_MOMENT subroutine in phys/module_mp_morr_two_moment.F file similar to rainprod/evapprod in line 575. 2. Added 'EFFC' in line 140 and...
