Hello! When using OBSGRID, I have a question regarding running ./get_rda_data.exe. After downloading the upper-air and surface observation data (ds351.0 and ds461.0), I merged all files using the command cat *OBS:2023* > rda_obs. The upper-air data files are named OBS:YYYYMMDDHH, while the...

Hello! I would like to ask some questions about OBSGRID. Question 1: According to the official user guide I've read, it says that the observation data has a time interval of 6 hours and after downloading, it needs to be split into 3-hour intervals using get_rda_data.exe. Is this a necessary...

Good morning from Chile. I would like your assistance with this; using WPS4.1; I'm a computer specialist, and not an Earth-science minor/major, so I'm a bit in the dark regarding this. We are trying ro create a set of nested domains for Antarctic continent (Antarctica/Antarctica); I'm also...

I am running WRF using WPS 4.4 version and would like to run metgrid using dmpar. As a result of searching through previous posts, I saw many people recommending serial because its performance is not bad. However, since we are trying to reduce the WRF execution time as much as possible, we are...

I am trying to ingest city specific urban canopy parameters that I developed using buildings heights and footprints data. The UCPs I built were: 1) Mean Building Height, 2) Distribution of building heights for 5m bins, 3) Area weighted mean building height, 4) Standard deviation of building...

I'm using noahmp and I have downloaded all the geography files located at this website: Static Data Downloads But I am getting this message when running geogrid: Parsed 67 entries in GEOGRID.TBL Processing domain 1 of 2 Processing XLAT and XLONG Processing MAPFAC Processing F and E...

Good morning everyone, I am thrilled to announce a secret project that Jiri Richter and I have been working on to enhance the NSF NCAR - The National Center for Atmospheric Research's Weather Research and Forecasting Model #WRF. The WRF Domain Wizard, a cornerstone tool for meteorologists and...

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...

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: 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...

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: [zkq@ustc WPS-4.3.1]$ ./metgrid.exe Processing domain 1 of 3 Program received signal SIGSEGV: Segmentation fault - invalid memory reference. Backtrace for this...

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!!!
