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...

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...

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...

Hello, I am an undergraduate studying numerical model in university There was a problem while turning the wrf model The following error occurred while unribbing the grib2 file When I first ran the wrf model, I used Matthew in the online tutorial In 2016, the same year, it worked well even...

Hello everyone, I'm trying to switch my landuse from Modis to Corine and having this error "ERROR: MMINLU values differ among input fields. Based on reading LANDUSEF using entry 3 from GEOGRID.TBL mminlu = MODIFIED_IGBP_MODIS_NOAH but a previous GEOGRID.TBL entry resulted in mminlu being set...

Hi everyone, I am trying to increase water friendly aerosol number concentration over the Great Barrier Reef to test the sensitivity of clouds to aerosol loading. The Thompson Aerosol Aware microphysical scheme is applied, and auxiliary aerosol climatology is used...

Hello everyone! I compiled WRF successfully, but I have trouble compiling WPS which no geogrid.exe, ungrib.exe, metgrid.exe were generated.I attach my configure.wps file and log.compile file below. Actually, I found something strange in the configure.wps file which are the 'COMPRESSION_LIBS' and...

Hello, I am trying to initialize a wrf run with HRRR data from NOMADS. I keep running into an issue during the metgrid step in WPS where it can't find ST values or even PRES. I noticed someone else was having an issue with this before, see here: Missing values, but mentioned they solved it...

Hi All， I am moving on to the static geographical data with WPS version 4.2 for a specific region ranging from -60S to 90N latitude and -180W to 180E, with spatial resolution of 0.25 degree. But after running geogrid.exe, the static data generated covers the entire globe from -90S to 90N. Could...

I have just run into a new problem when trying to run ungrib on some NAM grib2 files. the program creates the temporary PFILEs, but cannot proceed with the reprocessing, with the following message: forrtl: No such file or directory forrtl: severe (29): file not found, unit 10, file...

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!!!

Hey everyone I want to do a run using 2 nested domains, but I don't know if it exists any minimal distance between the parent and child domain boundaries. For example, in the attached image I have 2 domains, and the skyblue lines are the distances. Is there any good practice relationed with that?

Hey, everyone, I would like to know that if my initial boundary conditions are the GFS, there will be some difference in the result if I use the whole domain of the GFS (global) or if I only use one area, for example only South America I want to do downscaling to the GFS forecasts

Dear all, I am trying to use the MPI-ESM1-2-HR ssp858 and apply the dynamical downscaling. To convert the nc file to intermediate files I am using the python script provided GitHub - lzhenn/cmip6-to-wrfinterm: tools to process cmip6 data to drive wrf. I successfully create the intermediate...

I am trying to run limited-area MPAS simulations over the south-central USA. However, having difficulties setting up a domain for the WPS. Any tips regarding the WPS namelist will be much appreciated. Thank you.

Hi I want to use ERA5 ensemble members for I.C and B.C. I downloaded surface and pressure data from "Copernicus Climate Data Store |," but there are 10 ensemble members in a single file. I tried using "cdo splitsel,1 ERA5-pl_membsers-20210831-20210831.grib ERA5-pl_membsers-20210831-20210831_"...

Hi, I'm getting the following error while running ./ungrib.exe *** Starting program ungrib.exe *** Start_date = 2023-05-31_00:00:00 , End_date = 2023-05-31_06:00:00 output format is WPS Path to intermediate files is ./ ERROR: Grib2 file or date problem, stopping in edition_num. i had...

Hello all, I am at the WPS stage of a WRF version 3.8 simulation over the Atlantic using ERA5 boundary conditions collected from the NCAR site below: NCAR RDA Dataset ds633.0 I use their surface data, pressure level data, and two invariant files for LANDSEA mask and geopotential/soil height...

Hi, I am Grace, new to WRF and MPAS. I need WRF-WPS to build initial data for MPAS model. After compling WRF, I run the command ./configure under WPS directory, but get the following error: Error: The $WRF_DIR environment variable was set, but the WRF code at...

Hi, forum I am trying to ungrib ERA5 surface and pressure data downloaded from Copernicus Climate Data Store |. When I ungrib the data the PFILEs are created but then I get the following error. *** stopping in gribcode ***\n \tI was expecting a Grib1 file, but this is a Grib2 file. \tIt is...
