ungrib

Hi everyone, I’m working to initialize an MPAS run using initial conditions from the full ERA5 reanalysis dataset. Since my simulations target much higher altitudes (>100 mb), I’m using the 137 model levels rather than the standard 37 pressure levels to achieve higher resolution in these upper...

Hi, I am running ./ungrib.exe of WPSv3.9.1 (WRF Preprocessing System) in a NCAR Derecho HPC. It used to run fine previously without any errors within the same directory. All the required files are in the directory. I use era5 data from ‘/gpfs/csfs1/collections/rda/data/ds633.0/’ for surface and...

Hi all, I'm having an issue with ungrib program while using the ERA-5 land data (ERA5-Land monthly averaged data from 1950 to present). I'm getting the following error message after running the ungrib program: *** Starting program ungrib.exe *** Start_date = 2017-03-01_00:00:00 ...

Hello! I’m currently trying to make ungrib files using ERA5 data and eventually want to make metgrid files. However, there are 2 types of ERA 5 data: pressure level data and surface level data. Can you enlighten me by answering the following questions? 1. We need to make GRIBFILE.* (e.g...

Hello I tried ungrib in WPS. As the picture shows, Vtable is unrecognized. What does the error "ERROR in Subroutine PARSE_TABLE" means? and How should I do next? Best regards.

Is there a way to configure the ungrib Vtable to read in only one layer of a 3D variable? We are working with multiple years and want to reduce input files to be 2D, if possible. Specifically, we are looking to just work with surface level MASSDEN, but currently we are running through all 50...

Hi all, I'm in the process of updating SSTs in the WRF v3.8 model but I'm running into WPS issues when attempting to convert GLSEA SST data from netcdf to grib. I'm aware that there are similar posts on this forum however, after trying out a couple of different options, I am still running into...

Hi all, As my title says, I am trying to use pywinter to generate intermediate files to be read in by WRF/MPAS-A. I can import the module in python via import pywinter But trying to import the subroutine import pywinter.winter Results in the following error: ImportError...

Please note: This is the same issue as this post: https://forum.mmm.ucar.edu/threads/ungrib-exe-not-generated-after-compiling-successfully-metgrib-and-geogrid-exe.9434/#post-21637 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...

Hi, I am attempting to ungrib ERA5 files in grib2 format, but I keep getting the error message Looking for data at time 2012-05-13_06 ERROR: Data not found: 2012-05-13_06:00:00.0000 When I run ./util/g2print.exe, it will read the grib2 files, but it only returns the date/time...

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...

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...
