wrf output

Hello, I am currently using WRF-ARW 3.9.1 for my forecasting needs such as solar and wind power predictions, and I'm considering an upgrade to WRF-Solar to enhance our solar irradiance predictions. Given the theoretical benefits, such as cloudiness, aerosol and solar radiation accuracy...

Hello everyone, I am using sst_update in WRF, and the model runs without issues. However, I have noticed some extremely low temperature values at the land-sea boundaries in the wrfout output, which is causing problems for my subsequent MEGAN calculations. I am not sure why this issue is...

Hello. I'm trying to run WRF and get this error when executing the "wrf.exe" file: -------------- FATAL CALLED --------------- FATAL CALLED FROM FILE: <stdin> LINE: 2033 QG, QG(NK).LT.0 ------------------------------------------- application called MPI_Abort(MPI_COMM_WORLD, 1) - process 0...

I am running WRF 4.6 in a global configuration, with WPS grid settings of map_proj = 'lat-lon' e_we = 361 e_sn = 181 This leads to DX and DY settings of 111177.5 for WRF. I need to normalise some flux variables by cell area for use in a subsequent modelling process. The description attribute...

Hi all! I am relatively new to the WRF and the WRF forums, so apologies if I make any errors in post formatting. I am making this post in reference to a boundary discontinuity I am noticing in my WRF precipitation output. I am running a triple nested simulation, and I will attach my namelist...

I wanted to know U value of roof or thickness of roof when using sf_urban_physics = 3. and how we can change it

Dear Support, In my idealized experiment, I added a land area with a terrain height of 2 meters and fixed soil moisture at 30%. The land surface scheme is Noah LSM, and the initial surface temperature is set to 301.65K (originally 280K in the code). However, when the model starts integration...

Hello, I am simulating a hurricane case, but the pecision of track, slp and max wind are still needed to improve. May I ask if introducing SST into model could improve the accuracy of the simulation? I use gdas1.fnl0p25 files to drive the model. Three fixed domains with resolution is 16,4,1...

Hi all. I'm using PRE-CHEM-SRC to generate file for WRF following the exercise2(NOAA - Global Systems Laboratory). Unfortunately the convert_emiss can't run well. So I had to write my own Python program to convert the .bin file generated by PRE-CHEM-SRC into the .nc format. However, when I...

Hello I would like to know how do I make wrf run some data and with this data give me a future forecast for 2 days ahead. Exemple.: I have input data that goes from 2024-01-06 to 2024-01-09 and i would like to get future output data, like 2 days ahead, so in the end I would have output files for...

hi all, i wanna ask i already run model wrf and on the wrfout i got vertical level in 44 level (botom_top = 44), for post processing i use arwpost and use option 0 for interpolation method (model level), because when i try to use -1 and 1 for height or pressure, the system can find the HGT or...

I used to use the meteorological model WRF. Recently, I added the chemical module and recompiled it. However, the wrfout file that should have been output hourly has been output every three days. When the chemical module is turned off, the hourly wrfout file can be output normally. I want to...

Dear all, I want to calculate the precipitation rate (mm/hr) from the WRF model output and validate it with hourly satellite observations (e.g., GPM-IMERG). After searching online, I learned from this conversation (Calculate precipitation from WRF model output) that I need to just add 'RAINC'...

Hi, I have basic understanding of how to run WRF but I am still new to running WRF simulations. I need to predict 'wind gust' with WRF using future CMIP6 data as initial and boundary conditions. However, most CMIP6 models do not have 'wind gust' as a variable. In that case, will WRF be able to...

Hi everyone, I am running a real WRF-LES case where I see many non-physical lines and waves in my wind speed (attached) and temperature plots which indicate that my run has gotten unstable at some point. This is not the first time that I am experiencing this (I have experienced the same in...

Hi all, I am a ‘long-standing’ WRF user, and I am facing a really strange problem (for me). I am using WRF in the COAWST framework, coupled model, but this is not important because it also happens with WRF standalone (pure installation). Here is the error with the discussion...

Hi everyone, Does anyone has an idea of how to extract temperature data from a skewT plot. I have tried different options from Python to hand tracing the data but has not been successful. I am interested in extracting the sounding file from this paper"Explicit Forecasts of Winter Precipitation...

When I was simulating WRFv4.5 model using Modis data, I changed the land cover type using MCD12q1 data. The WPS part did not report any errors and ran normally. The REAL also ran normally, but WRF reported too many input land use types errors, How can I fix the error? rsl.error.0006: INITIALIZE...

Hello everyone, I hope I can get your help from here. I am modifying the relevant code in WRF and want to output intermediate variables in rsl (the VPRM part in module_ghg_fluxes.F). Now I want to output the current simulation time when the program is running. For example, if I start simulation...
