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...

Hi guys, I'm currently learning to use WRF_VPRM. I carefully read the WRF_GHG manual and the WRF-CHEM user guide 4.4. But I have a question now, I use WRF-CHEM version 4.3, I hope to be able to run WRF-VPRM with chem_opt=16, use VPRM to provide fluxes and combine with other lists to calculate...

I used the same settings and files for ten days for real.exe and the wrfbdy file generated in V4.5.2 was only 7GB, but in V3.9.1.1 it reached 34GB! What caused it?

Hi, guys, I hope I can get your help. At present, I have successfully completed the operation of VPRMpreproc program, and got seven related parameters, such as LSWI, LSWI_max/min, EVI, EVI_max/min and vegetation_fraction_map. But these seven parameters are divided into seven files. So, my...

Here are the details. When I try to compile the WRF-ChemV4.5, alwsys failed to find the four .exe in mian. Thins is my /.bashrc and I will post other files in attachment. As you can see in errors_comp.txt , there are some mistakes "‘ Makefile:50: warning: overriding recipe for target `.F.o'...

Dear WRF-Chem officials I want to use WRF-Chem to simulate DMS and its impact on air quality. Although the user manuals do include some information about DMS, I still have many questions. As many articles mentioned, the sources of DMS include 3 main aspects: oceanic, anthropogenic and...

On this webpage https://ruc.noaa.gov/wrf/wrf-chem/tutorialexercises.htm Under exercise 1. There is only one option to download a namelist.input file. However, to run the WPS commands you need a namelist.wps. Did the link get removed by mistake @jordanschnell

Hello, This is a tutorial that will show step by step how to download the WRF-CHEM tutorial data located on the ftp site. Step 1: Open a new terminal window Step 2. Make a new folder called WRF-Chem-Tutorials mkdir WRF-CHEM-Tutorials Step 3. Move to the new folder created in the terminal...

I run the RUN.exe with no error . But when i look the rsl.error.000 I get one error don't make the run error but make its result not exact. open_aux_u : error opening wrffirechemi_d01_2020-02-01_00:00:00 for reading. 100 Have any friends meet this question? I really need your help ...

My WRF-Chem v3.9.1 used to compile successfully on Cheyenne. However, it is encountering compilation issues since the system was changed to Derecho. I have made changes to the WRF-Chem v3.9.1 code, so I cannot use a newer version of WRF. Here are the modules and directories loaded before...

Greetings. Could someone please tell me what variables are the mixture ratio of sulfate and black carbon simulated by wrf-chem model? Are they so4_a0X and bc_a0X? But which bin should I choose? Thank you in advance.

Hi, everybody I use meic2wrf to make wrfchemi, but when I run WRF-ChemV4.5.2, I found that it reports an error Error trying to read metadata, and then it's still running normally after that, but only the information of the weather variable is in the wrfout, and I would like to know what I...

Hi sir, Now I'm trying to run the preprocessor in WRF_VPRM using the version VPRMpreproc_LCC_R99. When I run it, part of the program is SMOOTHING: loess filtering. Now I want to know, can this smoothing step be skipped directly, and if not, do I need to provide data other than the MODIS data...

Hello, We are trying to run WRF-CHEM simulations using CMIP6 data from future predictions. We were wondering if there is any way to include fire emission ( future fire emission) data in our runs. Thank you very much in advance, Polyvios
