    Overlapping domains

    I am currently designing an OSSE using a single domain convection-allowing nature run and single domain control runs at the same resolution. The only difference is in the location and size of the domains - the nature domain occupies a much larger area. For ease of verification, I'd like to...

    Using the GlobeLand30 data to create the urban fraction in USGS land use types

    Hi all, A paper has a sentence"Land use types have a resolution of 1 km The USGS data, where the urban fraction uses 30 m land use data from GlobeLand30, divided by city proportion 31~33 three categories, corresponding to low-density, high-density urban areas...

    geogrid.exe stops without error with my own binary file

    Hi, all I'm trying to replace the MODIS land cover data with the high resolution data which has shape format. I changed this file with QGIS and made binary file with write_geogrid.c code which is in the WPS/geogrid/src directory. I moved this binary file into the GEOG directory to run geogrid. I...

    (Resolved) Why high-resolution terrain data does not match actual altitude?

    Hi, I have now made a three-layer nested domains simulation with a ratio of 1:3:3, the grid accuracy of the finest nested area is 1km, and then the longitude and latitude of my target site is very close to one of the grid points in the 3rd nested domain. The distance is only about ten meters...

    SST input resolution and LANDMASK

    Today I have noticed these weird squares in the simulations over the Adriatic. Turns out this is the consequence of the ERA5's SST resolution (which is, as are all ERA5 variables, 1/4 of a degree). My question is - what kind of impact can I expect from keeping the resolution of SST as-is...

    Adding support for CMA-GFS in WPS-V4.5

    The CMA-GFS grib2 datasets is now able to be ingested by the ungrib program. The GRAPES_GFS(here in after referred to as CMA_GFS), the new generation of Global/Regional Assimilation and Prediction Enhanced System which is independently developped by China Meteorological Administration (CMA), has...

    Using precompiled WPS and WRF on Derecho

    Hello, I was trying to generate a netcdf file that contains 0.25-degree landmask, land use type, and terrain information, which I thought would be achievable by just running the geogrid.exe with the global namelist setup (maybe needs additional interpolation process) without installing the...

    ERROR querying GRIB2 message = 5

    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...

    Changing terrain to an idealized shape - which static fields need to be changed?

    Hello WRF Forums, I have a question regarding changing a part of the terrain to an idealized shape, namely taking a mountain range and replacing it with a quasi-uniform (length-wise) shape with the same cross-section as the average cross-section. I know I could open up the binary topography...

    successfully execute ./metgrid.exe, but errors are encountered in the generated files.

    Hello everyone, I am using the FNL dataset, replacing the land cover data for D03, updating SST, and generating the met file. When running real.exe, I encountered the following error: d02 2015-01-06_06:00:00 Input data is acceptable to use: metgrid input_wrf.F first_date_input =...

    Create 12 category soil types

    Hi all: I am using bnu soildata to create 12 soil types based on USDA soil texture triangle.After create the tif ,binary and index file. But when i run geogrid.exe,it has error.Whem my category_max of index is 16 (because the WRF soiltype all seem to be 16 ),the error is...

    SOILHGT variable from ERA5 with ungrib

    Dear, I'm trying to run MPAS initialized with ERA5 data, which throws the error: ERROR: SOILHGT field not found in intermediate file ERA5:2014-02-08_00 I checked this intermediate file and the variable is indeed not there. From old posts I learned that ungrib.exe should calculate this variable...

    Nested and Coarse domain WRF Domain Wizard

    Hi everyone, first of all I hope that you are well, continuing, I am creating a coarse domain of 9km of resolution and a nested domain with 3 km resolution with the WRF Domain Wizard to make a new domain for WRF-NMM model, the doubt that i have is that, is there a way to see the coordinate...

    all three xxx.exe files did not generated when compiling WPS

    Hello everyone! During the installation process of WRFV4.5.1, I successfully completed the compilation of WRF. However, I encountered issues during the compilation of WPS. I did not follow the official website tutorial for installing WRF because the necessary libraries for WRF are already...

    Metgrid SST interpolation artifacts

    Hi all, I have a problem with the met_em* files generated by metgrid.exe similar to this post here: metgrid - SST interpolation artifacts (not solved). I want to run metgrid with meteorological data from ERA5 (prefix FILE:...) and climatological SST data from ERA5 (prefix SST:...). If I run...

    UNIS data (2m temp, RH) was not included in afterwork when I tried ungrib.exe.

    Dear everyone. I came here to ask one problem when I tried to ungrib files. I want to run WRF 4.3.1 with Local Data Assimilation Prediction System (LDAPS), which used in KMA. So I made a Vtable to ungrib grib2 files and get variables before metgrid.exe I thought everything went well in first...

    Problem with avg_tsfc.exe

    I want to calculate the daily mean surface temperature with avg_tsfc.exe (as described in The WRF Preprocessing System (WPS) — WRF Users Guide documentation). I followed the process described there. I see that everything works smoothly, and I get a message "*** Successful completion of program...
