I have noticed in the WPS folder of WRF that the namelist.wps examples are typically using Lambert projections.
But based on the user's guide section on namelist.wps ( The WRF Preprocessing System (WPS) — WRF Users Guide documentation ) some of these variables change and/or not needed when...
Please note: This is the same issue as this post:

However, I was not allowed to reply to that thread, so I am starting a new one. Also, the issue reported in the...
Hi
I was trying to run a simple one domain WRF simulation using FNL data. I was able to run ./geogrid.exe, but am encountering an issue when running ./ungrib.exe.
I executed:
1) ln -s ungrib/Variable_Tables/Vtable.GFS Vtable
2) ./link_grib.csh...
Good morning,
The WRF Domain Wizard is still recommended as a way to create namelist files for WRF and WPS and is hosted on the GSD website.
However, it has recently been taken offline.
So is there a new recommendation from NCAR on its replacement?
What other alternatives are there to...
GOAL: Use High-Resolution Rapid Refresh (HRRR) model data as input to WRF to recreate initial atmospheric conditions, specifically for temperature and wind conditions at a specific location of interest.
I am using hourly HRRR "0 hour forecast" analysis data as my meteorological data input to...
Dear all,
I was trying to execute geogrid.exe of WPS-3.9.1 by the command ./geogrid.exe, but the system did not show any message, and geogrid.exe cannot be executed, it just stuck forever as the screenshot shows.
When I tried to interrupt the progress manually by ctrl+c, the error message...
Hi Forum.
I am trying to run a wrf model for 6 months using ERA5 re-analysis data. For which I have downloaded the SST and Sea-ice-cover data from Copernicus Climate Data Store | Copernicus Climate Data Store , along with 10m u-component of wind, 10m v-component of wind, 2m dewpoint...

Hi, I tried to do the tutorial on this website and using GFS from this website. I completed the ./geogrid.exe but facing error while running ./ungrib.exe. This was the error log:
I have read this thread and website but still faced the same problem. Here I attached my files and logs. Thank you.
i'm having a problem when i perform metgrid.exe in WPS. No errors occured performing geogrid.exe and ubgrib.exe. Here is the error:

Hi everybody,
I'm having the problem that intermittently (and I haven't quite figured out the system behind when it does and does not happen), `calc_ecmwf_p` tries to allocate 2 ExaBytes of memory and (predictably) crashes. The line where this happens is the following...
I need help~
I attempted to replace the static data in WPS using the following steps:
Utilized "convert_geotiff -t 5000 albedo.tif" to convert the tiff to GeoTIFF data. Modified the index of the resulting binary data as follows:
projection = regular_ll
known_x = 1
known_y = 3546
known_lat =...
Hi, everyone!
I got a weird problem when I run WPS. Sometimes some grids become 0, but sometimes don't.
But I use the same namelist.wps
Could anyone help me to solve this problem?
Thanks!!!
Hello,
First of all, I want to express huge appreciation for this forum.
Even though it's slow, I'm getting ahead with WPS-WRF based on this forum.
I had issue in conducting "ungrib.exe" , and the error message was [error while loading shared libraries "libpng12.so.0"
As a conclusion, I was...
Hi
I am running a two-way nested simulation for quite a large area (see namelist.wps attached) and for quite a long simulation (1980-2014). I am now to run metgrid.exe and am curious as to whether there will be any value running metgrid.exe in parallel with mpirun. I hope someone can provide...
Hello,
I am trying to run the attached batch script for namelist.wps. This may run ungrid, metgrid and geogrid in a remote server. But I am getting the following message when I change the meteorological data directory.

I am trying to run the aerosol-aware version of thompson microphysics scheme with mp_physics = 28 option. I am following all the instructions and have correctly used all namelist settings and aerosol data required. The metgrid.exe ran well and I can see the aerosol variables from...
Hi, I downloaded meterological data in csv fromat , how to conver it into grib2 so that "ungrib.exe" can read it .
I have tried :
import pandas as pd
import cfgrib
data = pd.read_csv('your_csv_data.csv')
xarray_data = data.to_xarray()
cfgrib.to_grib(xarray_data, 'out2.grib')
its not working...
Good day dear colleagues,
Please I would like to know if the Global Land Cover Characteristics - GLCC data (GLCCGBE20, with Geographic projection) on earthexplorer.usgs.com is the same as the usgs_30s data in WPS. If it is not, can anyone send a link to where it can be downloaded from?
Thank...
