running wps

I found a little disconnect between the online tutorial PowerPoints and the users guide online. Does Lambert projection true lat values need to be fixed at 30 and 60 degrees or can they vary?

Hello, I got the following error while running ./ungrib.exe .I downloaded the era5 data from NCAR research data archive . I have attached the namelist.wps and error file below. Do I need to provide Vtable for both pl and sfc data? I linked both datas using command. , ln -sf...

Hello. I'm running WRF for the 3 nested following meshes with ndown. First mesh: 5.55km resolution - 411x391 nodes Second mesh: 1.11km resolution - 1496x1411 nodes Third mesh: 370m resolution - 3829x3451 nodes The third mesh is a subregion of the second one and the second a subregion of the...

I am attempting to run WPS for a later WRF Solar simulation using GFS data as an input, however, after looking at the Vtable.GFS, I couldn't find any entries listed for cloud-related variables (cloud fraction, cloud water mixing etc). I assume I have to edit the Vtable to fit my needs, but...

I was using NUDAPT dataset provided on the WPS_GEOG data website for running BEPBEM WRF simulations. I later developed my own set of UCPs required from the explicit building footprints and building heights data we had. I followed some of the older documentations of NUDAPT...

Hello. I am trying to run a model using GEFS as input data for WRF. GEFS has gec00 (control forecast), gep01 ~ gep20 (ensemble member forecast), geavg (ensemble average) data, and I want to use geavg, which has an ensemble average. Based on the post below, if I ungrib the gep01 data to...

Hi, Im trying to execupte the WRF model for a 3 domain , this 2 nests, 1 in 1 in 1, one way nesting: Though I successfully execute the ungrib and geogrid steps, I get the following errors in metgrid - file name: namelist.wps [wrf_try]$ ./metgrid.exe Processing domain 1 of 2 Processing...

Hi I'm trying to run a short case with GFS as initial and boundary conditions I downloaded the files from RDA/NCAR dataset ID: d084001, I run WPS setting Vtable.GFS and METGRID.TBL.ARW. When I run it is shows no problems, but the met_em files are missing PSFC and ST0000010 (and the other ST#...

**Guide to Using Copernicus ERA5 Data with WRF** Dear WRF Users, Many users encounter challenges when utilizing ERA5 data from the Copernicus Climate Data Store (CDS) with WRF. To assist, I've put together a step-by-step guide on how to successfully download, process, and run ERA5 data within...

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...
