running wrf

Hello. I'm beginner to the WRF model. I was wondering about the default timezone in WRF. If I use a UTC-based input, the output will be in UTC, no matter where the domain is located, right? So if the model start time is 00:00 UTC on 1 October 2021, will the solar insolation or altitude in the...

Hello everyone, I want to run wrf.exe (WRF-Chem) with one-way nesting because of the limitations of my system (a linux server with 378 GB of RAM and 32 processors). I have gone through the WRF user guide, which explained how to do one-way nesting using 'ndown.exe'. Also, I found the following...

Hello, I'd like to know if it is possible to use an environment variable to direct the output files from wrf.exe and if so, what the syntax would be in the namelist file. I'm thinking of something like the following: &time_control ... history_outname =...

Hello, I am attempting to run nested (9km x 3km x 1km) urban simulations with the use of the mosaic landuse categories option. The simulation is stable and the output is realistic when I initialize and integrate the model forward in time. However, whenever my compute limit is reached and I...

Dear colleagues, (1). Please, how can I ensure that my simulation has a fine vertical resolution? (Vertical height above the ground). The e_vert? (2). How can I ensure that the values of snowfall and snow coverage are reset to 0 before each integration? (3). How do I exclude un-needed...

Hi, I have been trying to run some WRF runs but keep getting the attached rsl.error (same for every processor). I have already done WRF runs with input file created in WPS from the same original input data (HadGEM2-ES) for the dates 27-3-20* till 31-5-20* which ran without an issue. But for...

Hi all, I am running the WRF-Noah MP model in East Asia during 2021.6-2021.8 without any errors reported. However, I found some strange things in my wrf.output files: (1) Strange time dimension. Generally, my daily wrfout files have a dimension of 159*159*1 (My study area covers 159 grid...

Dear colleagues, I came accross this (the attached picture) in the Noah-Mp technical note documentation can anyone explain the extra terms for the Lagv? Thank you for your help in advance.!

Can WRF-ARW perform a 3 day forecast based on historical data? I am trying to run wrf model beyond the given input days but it is getting stopped.

Hi all, I was trying to run real.exe, but it exited with code 1. I downloaded real-time data (fnl_xxxx_xx_xx.grib2) from NCEP FNL Operational Model Global Tropospheric Analysis online data sets. I successfully ran geogrid.exe, ungrid.exe, and metgrid.exe. but failed in initializing to generate...

Hi everyone, I am having an issue with running my WRF model on two clusters with 35 nodes each. I set the maximum time limit to 24 hours, but my model runtime is 152 days, or about 3 months long. As a result, I've only been able to run and output about 9 days out of the 152 days. I had to...

Hello, my question is the following. If I run WRF with MPI and other nodes (Cluster ) is the execution time shorter? I did a test and it seems to me that I didn't see any difference in execution time. I don't know if I did something wrong. My test was as follows First I used a node with 8...

Hi everyone! I was running WRF-Chem3.9.1 with KPP, reinitialized the meteorology every 24 hours but with chemistry field from previous time step when doing re-initialization. After running several days, a SIGSEGV occurred (see all_rsl.error.txt attached). Since I found in the error log file...

Hi, WRF forum! I am a WRF beginner. From what I understand so far, I can only produce results /simulations for just the same timeframe as the forcing dataset ( and selected in the namelist.input & namelist.wps). Assuming I do not want to force with future projection datasets like the Bias...

Hi, I'm getting the following error when i run real.exe. I have attached error image, namelist.wps , namelist.input and rsl error file

Dear all,

Hi all, I have a doubt in the met_em files generated. I'm trying to reproduce the results of the simulation from the article -"Recovery processes in a large offshore wind farm". I'm using WRF 4.4.1 and WPS 4.4 for the current simulation. I have successfully compiled the WRF and WPS with the...

Dear friends. I compile "nmm_tropical_cyclone" under "wrf/test" (First use the command "./configure ", then "./compile nmm_tropical_cyclone" in "WRF"). In the process, there are frequent warning and two errors at the end, so “ideal.exe” cannot be generated, but “WRF.exe” can be generated...
