wrf.exe

Hello there, This post is tangentially related to a previous post I made (found here). In that post I detailed how the ERA5 data I was using showed the Guadeloupe, Dominica, Martinique, etc. islands within the SSTs (being 0 Kelvin) but did not appear in the landmask. After being stumped on...

Hello ! I want to replace the static data of LAI, ALBEDO, and LU_INDEX in WRF. I chose to directly replace the geo_em.d02.nc data. After the replacement is successful, both metgrid.exe and real.exe can run successfully, and the resulting data is fine. However, in the final step of running...

Good morning everyone, I was wondering if WRF output can help calculated some aviation weather parameters or if anyone knows how to calculate them with WRF python? I am looking for these parameters: - Freezeing Level - Cb potential - Turbulence potential Please let me know if you have any...

Hello all, I'm running WRFV4.5 with sf_urban_physics=1 (i.e., SLUCM), unfortunately, the model stopped after integrating several hours. The error information which I got is as follows: [ib0414:86410:0:86410] Caught signal 11 (Segmentation fault: address not mapped to object at address...

Hi all, I am running the WRF model with UCM over eastern united states. The problem is the errors I am facing with UCM. The model works with UCM off but when the UCM is on it will stop after a few hours or even days. I attached the namelist and rslerror files.

I am currently using WRF 4.5 to perform regional climate simulations over the Tibetan Plateau. However, I consistently encounter an error when running wrf.exe: Program received signal SIGSEGV: Segmentation fault - invalid memory reference. Backtrace for this error: #0 0x151d5f527ad0 in ??? #1...

Hi everybody, I appreciate all the answers provided by this forum, it helps with the model. I am pretty novice on WRF and MLUCM simulation. However, it seems that i have a problem running WRF with sf_urban_physics = 3 and use_wudapt_lcz= 1 I used w2w tool to generate geogrid file with lcz map...

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...

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 =...

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...
