wrf-chem

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...

Dear Colleagues, We are pleased to invite abstract submissions to the session 68966, "Wildfire Influence on Aerosol, Cloud, and Climate," for the American Meteorological Society’s 17th Symposium on Aerosol Cloud Climate Interactions to be held on January 12 - 16, 2025, in New Orleans, LA...

Hello WRF-GHG Community, I'm excited to share a new resource that I hope many of you will find useful: “WRF-GHG User Guide.” You can access it via this DOI link: 🔗 WRF-GHG user guide - Repository of BIRA-IASB What’s Inside? This guide offers a comprehensive overview focused on the greenhouse...

Hello, I am trying to use mozbc to input dust data to the wrfinput file. This correctly works, and the dust data shows up in the wrfinput file. The problem is that when I run WRF-Chem, the first wrfout file does not contain any dust information. It basically starts the dust variable from...

Dear all, I am running WRF-Chem version 3.9.1 using RADM2-MADE/SORGAM as a chemistry option (chem_opt=2). After getting the successful run, I found the following variables related to organic carbon in the model output: float orgaro1j(Time, bottom_top, south_north, west_east) ...

The program got stuck without any error message. No output or log entry appears even after 20 hr. I had to kill the program forcibly. The last few lines of the rsl.error file are: “d01 2024-04-01_00:00:00 calling conv transport for chemical species d01 2024-04-01_00:00:00 calling calc_het_n2o5...

Hello, I wish to use WRF-Chem V4.5.1 together with the CBMZ/MOSAIC chemistry option on two nested domains over Eastern Europe for a simulation of 54 hours. However, the run stops after some time whenever I select aerchem_onoff = 1 for my domains in order to include aerosol chemistry. The run...

Dear community, I am running wrf-chem 3.9.1 version with sfc_urban_physics=1. But it stops at the first running time when dealing with domain2. It shows forrtl: error (78) in rsl.error. However, it ran sucessfully with sfc_urban_physics=0. I tried some tests. when 4 nodes ,per nodes with 64...

Good day from Tokyo. Our university supercomputer was recently upgraded, so it's also high time to compile the updated versions of WRF. Following the procedure for compiling WRF-Chem with the KPP seems to go smoothly (see attached compile.log). However, for more than a day of leaving it to...

Hello admins @islas @weiwang @kwerner @jordanschnell , @mgduda With the release of WRF v4.6.0, I have conducted a series of evaluations on the Weather Research and Forecasting Model Chemistry (WRF-Chem) version 4.6.0, utilizing the Intel LLVM Compilers and associated libraries. The purpose of...

Hello everyone: When I was working on the cycle mode of WRFDA, I conducted data assimilation at 0:00, 6:00, 12:00, and 18:00 respectively. I found that after completing the assimilation at 6:00 and linking to the WRF running directory, the namelist should be integrated from 6:00 to 12:00...

Hi,all! I have used the MOZCART(chem_opt=112) mechanism to stimulate a case. However, I found that the PM2_5_DRY and PM10 variables in the first output wrfout file will always be 0, and also the P10 and P25. I have checked the initial condition file and boundary file of my stimulation. The...
