    Problems in LU_INDEX in nested domain

    Hello! I'm running a simulation using a namelist provided during a wrf tutorial (attached below) which uses the NLCD dataset for static data. Everything seems to be ok for the first domain, while the second domain shows some problems with the LU_INDEX variable (see the image below). I noticed...

    WPS WRF simulation time period difference

    Hi, I would like to know if it is compulsory to keep the simulation time period between WPS and WRF same. Can I run WPS for certain time period range (say 01-Jan-2020_00 to 03-Jan-2020_00) and do different runs of WRF with different starting time (eg: Run-1: 01-Jan-2020_06 to 03-Jan-2020_00...

    .p000 files when running metgrid.exe and real.exe not working after

    I am trying to run a WRF with a very large domain at 4 km. Running metgrid.exe on Derecho produced *.p000 files that I hadn't seen before. It appears that metgrid.exe runs correctly and auto-deletes the .p000 files. I then go to run real.exe, and I get the attached error before real.exe...

    Metgrid run with dmpar (parallel run)

    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...

    Is it recommended to use the same spatial resolution for all surface parameters?

    Dear users, The WRF model has 30 arc-seconds (~900 meters) as the higher spatial resolution by default. I read many papers where authors changed the topography (HGT) to a higher resolution (e.g. 90 meters). I also managed to change it. But now I have a question. The another surface parameters...

    Land-use categories

    Hello WRF community, I would like to make changes in the spatial distribution of land use in WRF. Instead of using MODIS, I will use an updated national product for Chile (LU-CL). For this purpose, I will modify the LU_INDEX variable. Obviously, I will use the same categories as MODIS...
