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？

I am a student new to WRF. I want to perform simulations that consider irrigation conditions. I have added the IRRIGATION content in the GEOGRID and downloaded the IRRIGATION data in the static geographical data. Verification shows that the IRRIGATION field has been successfully integrated into...

I’m simulating the urban heat island with WRF 4.4.1 and have encountered problems about different URBPARAM*.TBL files used in UCM. I’d appreciate any clarification on in what cases will each of these files takes effect. I understand that the sf_urban_physics in namelist.input controls whether...

Greetings, I've been troubleshooting the past couple days trying to figure out a solution to the following error I'm receiving: I'm running WRF v4.6.1 -------------- FATAL CALLED --------------- FATAL CALLED FROM FILE: <stdin> LINE: 70 program wrf: error opening wrfinput_d01 for...

Dear WRF Community, I’m currently troubleshooting a persistent crash in WRF v4.5 that consistently occurs after the third model day, with the following error: I'm running at 15 km resolution, using Noah-MP (sf_surface_physics=4) and the following physics setup: What I’ve Tried and Observed...
