wrf output

I have successfully simulated meteorological results over a period of time and obtained the wrfout files. Now, I need meteorological data at a finer spatial and temporal scale. Can I use the existing wrfout as input to run WRF again to achieve this goal? Thank you in advance for your help!

Problem: I ran my WRF simulation with sf_urban_physics =1 and sf_urban_physics =0 and seems to show no difference in T2. I also got no errors,warning, or faults in my rsl file. I am using WRF v4.6.0. I think the urban canopy model (UCM) is not activating because it does not finds valid urban...

So I am trying to run a real case in WRF. The ungrib manages to read all files properly, with every field accounted for, including 10m wind speeds. Metgrid also succesfully computes surface level, apparently. But the thing is, in some land points, WRF is not generating wind speed at 100m high...

Hi everyone I am working with co2 green house gases. I successfully ran mozbc tool for creating wrfinput_d01 and wrfbdy_d01 and also added anthropogenic activities by creating wrfchemi_d01 file now issue is that i did not find CO2_BCK parameter in my processed file. i set up the chem_opt = 301...

Hi everyone, I hope you're doing well. I’m looking for a tool or method to extract temperature and water vapor data from Skew-T plots like the ones in the link below: WRF Skew-T Plots If anyone has experience with this or knows of a suitable tool, I’d really appreciate your insights. Thank you!

I am getting an warning when trying to execute ./wrf.exe. The Input boundary data is d083003 Timing for main (dt= 15.00): time 2019-05-08_23:59:45 on domain 2: 3.34889 elapsed seconds Timing for main (dt= 15.00): time 2019-05-08_23:59:45 on domain 1: 3.89559 elapsed seconds Timing...

I am trying to run a simple WRF test on two different machines and am trying to figure out why one was successful whereas another was not. I am running the same test on both machines and am able to get all the way to wrf.exe on both. However, on the unsuccessful machine I get the following...

I've recently noticed that when changing the options in the WRF namelist, specifically between using NetCDF (option 2) and PNetCDF (option 11), both the file naming structure and the file sizes change. For instance, with PNetCDF (option 11), the file name follows the format...

I am getting extreme negative values of ground heat flux when i simulate 100% PV. I have atatched my Urban file and namelist.input

Hi, i need helping to extract output wrf to CSV by using NCL. How to extract Rainfall at a certain latitude and longitude? How to plot it? and How to merge 1 WRF output folder into 1 file? I already search the script but it does not work. Please send me the script, i wanna finish my study in college

Greeting, I tried to run the WRF model for five days for the first time. At the end of the result shown FATAL CALLED FROM FILE: <stdin> LINE: 1150 ---- ERROR: Ran out of valid boundary conditions in file wrfbdy_d01 Before running the program, I ensured that I had completed every step and...

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...
