running wrf

Hello everyone, First, sorry for my English. I hope you understand. See, I have a problem of Segmentation Error. I already saw many post about that and I concluded that it was because of inestability of the model, so I change my timestep of 60 to 30 and it worked. However, I seem the time of...

Hello, I am working my way through the online tutorial and I keep running into a segmentation fault for the 2-way, 1 input file nested domain run. Unfortunately these faults are not very useful when trying to debug so I was wondering if anybody else has run into a similar issue? What was your...

Hi All, While running WRF I'm getting p_top mismatch error. Timing for processing wrfinput file (stream 0) for domain 1: 32.93626 elapsed seconds Max map factor in domain 1 = 0.00. Scale the dt in the model accordingly. D01: Time step = 120.000000...

Hi all, I am new to installing the WRF model. I have a virtual machine with Linux RHEL 6.4, where I have previously installed WRF version 4.0.1, and I run the model daily for 48-hour forecasts. I have tried to install the WRFV4.4.2, but I get the following warning before compiling...

Hello. I'm trying to run the latest version of the WRF model by implementing the hybrid 100-m global land cover coupled with the BEP urban parameterization. I have 3 nested domains with 12 km, 4km, and 1km horizontal resolution, respectively. Unfortunately, during the simulation of the first...

We have a few positions at IIT Bombay that we seek to fill quite urgently under a newly funded project (PAVITRA—Air Pollution Management and Intervention Tool for India). Please see the job profile, and interested candidates may kindly apply through the below link: 1. Project Research...

Hi, I am trying to run wrf.exe (version 4.5) for a nested domain, but after a couple of minutes (and after writing the output of the very first time) the model stops with "segmentation fault". I do not see any CFL errors in the rsl files (or any error at all) even when I configured wrf with -d...

I meet this problem while getting an ideal case，rsl.error.0000 is like this： Ntasks in X 1 , ntasks in Y 1 IDEAL V4.1.2 PREPROCESSOR ************************************* Parent domain ids,ide,jds,jde 1 131 1 131 ims,ime,jms,jme...

Hi everybody, I appreciate all the answers provided by this forum, it helps with the model. I am pretty novice on WRF and MLUCM simulation. However, it seems that i have a problem running WRF with sf_urban_physics = 3 and use_wudapt_lcz= 1 I used w2w tool to generate geogrid file with lcz map...

Hi, I'm a student who just started learning about the WRF. I want to run the WRF model, but I can't run it due to an error. Attach the namelist and rsl files. I would appreciate it if you could let me know what the problem is. For your information, the data is using ERA5.

hello, i am trying to install latest version of wrf 4.5 which i downloaded from Github website. when i try to configure it. i install all libraries and give them All path everything is alright but it shows this error when i try to configure. can anybody help me with this? it show this error...

Hello, I've run WRF on private and public cloud platforms before and I'm looking for updated best practices for good simulation performance. Specifically, I'm planning to run a CONUS 2.5km benchmark (likely maria 1km as well) and then a Land Use Land Cover science case at around 1km grid...

Hi, I am using WRF-chem 4.4.1, but while running the wrf.exe, I am getting the following error. Timing for Writing wrfout_d01_2019-11-01_00:00:00 for domain 1: 32.39404 elapsed seconds mediation_integrate: med_read_wrf_chem_emissions: Read emissions for time 2019-11-01_00:00:00...

Hi all, I am not an atmospheric chemist, but I am an environmental modeler and wear multiple hats, including as a consultant. We have a project using a VOC/Ozone model around the globe, and so we are looking for global weather data. It appears WRF would be suitable, except for its learning...

Hi, I am using WRF-chem 4.4.1, but while running the wrf.exe, I am getting the following error. WRF NUMBER OF TILES = 1 d01 2017-11-01_00:00:00 ---------------------------------------- d01 2017-11-01_00:00:00 W-DAMPING BEGINS AT W-COURANT NUMBER = 1.000000 d01 2017-11-01_00:00:00...

When i used this command "mpiexec.hydra -print-rank-map -n 4 -machinefile hosts ./wrf_hydro_NoahMP.exe" in one machine in order to run wrf-hydro model in both two machines，it reported errors: i want to run this model in two machine and two processes run on each machine .Data directory for wrf...

Good day dear colleagues, Please I would like to know if the Global Land Cover Characteristics - GLCC data (GLCCGBE20, with Geographic projection) on earthexplorer.usgs.com is the same as the usgs_30s data in WPS. If it is not, can anyone send a link to where it can be downloaded from? Thank...

Hi everyone, I was confused about the warning messages for a long time. I really appreciate it if anyone can provide some suggestions on fix it. I used wrf_hydro_arcgis processing tools to generate routing files. During the process, I added a cvs file that lists the location of each forecasting...

Hi, I'm WRF model newbie. I'm running WRF model with 3 domains and I chose the physics suites named NCAR Convection-Permitting Suite. And I added the option Stochastic parameterization schemes. This is part of my namelist.input &stoch rand_perturb = 1, 1, 1, nens...

Good morning, Could someone please explain how to use e_Vert and the stretching variables? Like I have read the tutorials and I am still not sure how to use it properly. I have attached my namelist.input for someone to help me.
