wrf.exe

Hello, WRF Team Thank you for your contribution! I am running WRF-Urban with BEP/BEM. However, when running wrf.exe it quits after a few minutes. When I change sf_urban_physics to 2, the model runs fine, but I want to check the energy consumption values, so I have to set sf_urban_physics to 3...

Dear Forum Members, I'm experiencing difficulties running wrf.exe after successfully running ungrib, geogrid, metgrid, and real.exe programs. My setup involves utilizing ERA5 as input data and versions 3.7.1 and 4.0.3 for running WPS and WRF respectively on a HPC cluster. I have attached the...

Hi, I am using WRF-chem 4.4.1, but while running the wrf.exe, I am getting the following error. WRF NUMBER OF TILES = 1 d01 2017-11-01_00:00:00 ---------------------------------------- d01 2017-11-01_00:00:00 W-DAMPING BEGINS AT W-COURANT NUMBER = 1.000000 d01 2017-11-01_00:00:00...

Good morning, I have been exploring the namelist options for WRF and have come across the w_damping option. I have been trying to figure out when to use it or not use it for WRF. Looking at other peoples namelists on the forum I really don't see any consistent times on when to use it and...

Hi, I'm WRF model newbie. I'm running WRF model with 3 domains and I chose the physics suites named NCAR Convection-Permitting Suite. And I added the option Stochastic parameterization schemes. This is part of my namelist.input &stoch rand_perturb = 1, 1, 1, nens...

Good morning, Could someone please explain how to use e_Vert and the stretching variables? Like I have read the tutorials and I am still not sure how to use it properly. I have attached my namelist.input for someone to help me.

In practice does e_vert need to be larger than num_metgrid_levels or can they be the same?

I'm trying to run wrf.exe using WRF-4.3.1. All WPS and real.exe were completed successfully. When I try running wrf.exe. I end up with the error below in rsl.out.0000. Attached the namelist file I'm trying to use. Many thanks in advance. Edit: I have also tried with sime_step = 162 seconds...

Hello everyone, I am running a wrf model with this publicly available data from https://nomads.ncep.noaa.gov/pub/data/nccf/com/gfs/prod/gfs.20230313/00/atmos/. wrf.exe completed successfully in 34 hrs using 20 mpi processes. I was trying to reduce the runtime by increasing the number of mpi...

Would someone do me a favor? When I run wrf.exe ,"ERROR reading namelist namelist_quilt" is displayed. I have attached my namelist.input and rsl.error.0000. Thank you very much！

Hello everyone, As shown in the title, I am faced with a perplexing problem using wrf.exe. This problem does not usually occur, but it does occur in certain area settings and with a limited number of parallels. I'm using dm+sm mode. 16 MPI and 9 OMP threads/process -> NG 16 MPI and 18OMP...

Hello everyone, I want to run wrf.exe (WRF-Chem) with one-way nesting because of the limitations of my system (a linux server with 378 GB of RAM and 32 processors). I have gone through the WRF user guide, which explained how to do one-way nesting using 'ndown.exe'. Also, I found the following...

Hello, I'd like to know if it is possible to use an environment variable to direct the output files from wrf.exe and if so, what the syntax would be in the namelist file. I'm thinking of something like the following: &time_control ... history_outname =...

Been having issues using the intel compilers with WRF and WRF-Chem only within the last 24 hours. Not sure if intel changed something on their compilers or if the WRF packages had a change but the module_firebrand_spotting_mpi.f90 doesn't exist. I have attached the configure.wrf and...

Not sure what the issue is. First off the namelist files are not mine, I am trying to use them and adapt to my needs. So there may be something I am missing that I do not know. I have attached all the rsl.error and rsl.output files from ./WRF and ./REAL as well as the namelist.input for WRF.

Hello Been trying to resolve this error issue by looking for answers somewhere else in the internet, but to no avail. I am running WRF-Chem with anthropogenic emissions from EDGAR-HTAP and bio emissions from MEGAN, all the tools necessary before running WRF-CHEM, such as anthro_emis...

I have tried following several tutorials online and I am not getting any success installing WRF v4.4.2, v4.0.0, or v3.9. All environment and compatibility tests pass with libraries. Libraries being used: zlib 1.2.13 hdf5 1.14.0 netcdf-c 4.9.0 netcdf-fortran 4.6.0 mpich 4.0.3 libpng 1.6.39...

Hello, I already read multiple posts on this forum quoting this error but none of the provided issues to check or solution to try seemed to work (e.g. : no CFL error). I'm using inputs from ndown.exe (originating from wrfout* by WRF 3.6.1) into a 2-domains (121x121) nested run by WRF 4.2.1...

Hello everyone! When I run wrf.exe (Version 4.3.2) with gwd_opt equals to 3 in namelist.input, all the relevant diagnostic variables are zero, and the wind fields of all three domains (25km, 5km, and 1km)are exactly the same with gwd_opt equals to 0. According to the users' guide, gwd_opt...

Can WRF-ARW perform a 3 day forecast based on historical data? I am trying to run wrf model beyond the given input days but it is getting stopped.
