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.

I was searching for sf_ocean_physics at the Forum and I found this thread: problems running WRF with sf_ocean_physics option 2. Is mentioned that options 1 and 2 doesn't recognize the difference between land and sea. Mr @jcarlosgm solved that masking and using a conditional. Can someone give me...

In practice does e_vert need to be larger than num_metgrid_levels or can they be the same?

I'm trying to run wrf.exe using WRF-4.3.1. All WPS and real.exe were completed successfully. When I try running wrf.exe. I end up with the error below in rsl.out.0000. Attached the namelist file I'm trying to use. Many thanks in advance. Edit: I have also tried with sime_step = 162 seconds...

Hello everyone, I am running a wrf model with this publicly available data from https://nomads.ncep.noaa.gov/pub/data/nccf/com/gfs/prod/gfs.20230313/00/atmos/. wrf.exe completed successfully in 34 hrs using 20 mpi processes. I was trying to reduce the runtime by increasing the number of mpi...

https://forum.mmm.ucar.edu/threads/how-many-processors-should-i-use-to-run-wrf.5082/ The python code in this forum thread is meant for HPC systems. If I have a desktop or laptop what values need to be changed to the python code??
