Hi all — I’m seeing a reproducible WRF-Chem/KPP build stop that looks like an internal consistency issue in the CBM4 mechanism files During a WRF-Chem build (`WRF_CHEM=1`, `WRF_KPP=1`), the `chem/KPP/compile_wkc` step iterates over mechanisms and exits with: > `ERROR: variable name for third...

I am running the WRF model for an event using the urban physics scheme=1 and getting the below error. WRF model version: 4.5.2 Simulation period: 22/05/2024_00 to 27/05/2024_18 Timing for Writing wrfout_d02_2024-05-22_00:00:00 for domain 2: 0.52564 elapsed seconds Tile Strategy is...

Hi everyone, I am currently running some simulations in complex terrain. I have successfully run and validated a simulation using the Noah-MP Land Surface Model without any issues. Now I want to study the effect of using different LSMs. When I try to use the RUC LSM, wrf.exe crashes...

Hi, all. I'm using WRF-NoahMP from 2009-2014 to simulate irrigation in Xinjiang, China. However, model got the Segmentation fault when wrfout_d02_2010-01-07_10:00:00. My WRF version is 4.6.1 using ERA5 data as forcing data, and I'm using 120 cpu to run my case. Hope you can give me some help...

Came across a new dataset which is promising, will we be able to use the MSWX dataset for running WRF?

Hi, I'm using run_wrf.pbs to run a WRF simulation. Originally, I use this parameter set in the .pbs file: #PBS -l select=8:ncpus=30:mpiprocs=30:mem=64GB But it was running slow, so when I restart this job I changed the parameters to increase node number: #PBS -l...

Using the ECMWF Climate Data Store (CDS) to Download ERA5 Data in a Conda Environment This guide shows you how to: Create a Conda environment called CDS with pip and cdsapi Activate the environment Set up your CDS API token (.cdsapirc) Use the Python script Download_CDS_ERA5_Data_Hourly.py to...

I am attempting to run three separate WRF runs, all of which are unsuccessful and throw the same errors: "rank XXXX died from signal 11" and "rank XXXX died from signal 15." A quick search reveals these are segmentation faults, with signal 11 indicating an MPI segmentation fault. Screenshots of...

Hello WRF community, I have been using WRF for a year-two now, and now I would like to start altering the WRF code. My goal would be to add or alter a physics package, so I would like to ask for any materials you found useful in the following steps: Defining and ingesting new data (e.g...

Hello all, I'm using WRF-Solar shcu_physics=5 (Deng) to simulate the shortwave radiation conditions over the whole China, but got a "segmentation fault" error, it seems like this error is related to the Deng shallow cumulus scheme. I'm not sure if I might have missed some parameter settings...

Dear WRF community experts, After modifying microphysics, cumulus convection, and other physical parameterization schemes in namelist.input, if I need to compare simulation results from different schemes, is it mandatory to rerun real.exe to regenerate the WRF initial field files? Or can I...

Hi everyone, I have been trying to run real case scenarios (12 km -- 3 km -- 1km) over the city of Bhubaneshwar following some idealised simulations I ran over this city. I try to deviate as little as possible to my idealised simulations configuration but I am facing issues. The model runs only...

Dear WRF team, Before posting this question, I made every effort to search the forum for relevant information. However, I was unable to find a solution, so I am posting this thread to seek assistance. I plan to use WRF-BEM to simulate air-conditioning energy consumption at the urban scale. The...

Hello everyone, I am running a 3 day case in urban areas, but always stopped at around 19:00 of the second day, the error is: " WARNING: critical problem: ZLVL <= ZPD; model stops -------------- FATAL CALLED --------------- FATAL CALLED FROM FILE: <stdin> LINE: 4644 STOP in Noah-MP...

Hi everyone, I’m trying to include several atmospheric heating rate variables in my WRF-SLUCM-v4.4.1 simulation output. To do this, I created a text file and added the following content: I then specified the file in namelist.input under iofields_filename, with ignore_iofields_warning = .true...

In my WRF simulations, if in the nested domain (i.e. 3rd domain) dt crosses 0.1 sec then CFL error is coming. Whereas, 1st and 2nd domain can run sucessfuly with dt=15 sec. Therefore, is there any way to restrict the timestep differently in different domain? I am also wondering is an adaptive...

real.exe runs successfully, but when I try to run wrf,exe gets the following error. Please help me to resolve this issue INITIALIZE THREE Noah LSM RELATED TABLES Input data is acceptable to use: WRF NUMBER OF TILES FROM OMP_GET_MAX_THREADS = 1 Tile Strategy is not specified. Assuming 1D-Y...

WRF-4.5 I'm simulating three domains as set in the namelist.input1, for a 700 mm rainfall event in one day, rainfall starting at 9 am. Initial data is from ERA5. The simulation only runs successfully if I simulate the first two domains, so I used ndown to simulate domain d03 separately. I ran...

Hi everyone, I have geo_em files generated by WPSv4.4 that include urban building information. Using Python scripts, I converted the "LU_INDEX" and "LANDUSEF" in the geo_em files to make them compatible with WPSv4.5. After running the full workflow in WRFv4.5.2, the results suggest that building...

当我使用 Modis 数据模拟 WRFv4.5 模型时，我使用 CGLC-MODIS-LCZ_100m 数据更改了土地覆盖类型，其中 NUM_LAND_CT=61. WPS 部分没有报告任何错误，运行正常。 REAL 也正常运行，但 WRF 报告了太多输入土地利用类型错误，如何修复该错误？
