    Change in Mandatory Static Data

    Hello WRF community, I am running a simulation with two domains: d01 with 9km resolution and d02 with 3km. In the near future I will add a d03 with 1km resolution. Previous studies in the region of my domain show that changing the default WPS topography to ASTER with a resolution of 1s (90...

    Nested and Coarse domain WRF Domain Wizard

    Hi everyone, first of all I hope that you are well, continuing, I am creating a coarse domain of 9km of resolution and a nested domain with 3 km resolution with the WRF Domain Wizard to make a new domain for WRF-NMM model, the doubt that i have is that, is there a way to see the coordinate...

    Geogrid topography

    Hi I tried to insert srtm data 3s in geogrid. It works fine. But i didn t understand why if i plot HGT_M from geogrid nc file i see flat map and i didn t see any big difference respect to the default Attached a picture . Could be the way to plot HGT_M? Have you specifica script?

    error while run geogrid.exe

    When I running geogrid.exe, it keeps getting killed. For some reason, I think there should be no mistakes in my namelist. mpi didn't work either. I've reinstalled it multiple times, and it's WPS4.0. And there is no error message in the log. By the way, I'm running the wrf model with a server, so...

    (RESOLVED) Troubles trying to change from MODIS to USGS data

    Hello, Although I read the User's Guide and did as explained, I can't make WPS to use USGS data instead of MODIS. I need to try and use USGS because of ndown/WRF.exe issue (using old coarse run under USGS as input via ndown.WRF.exe for a finer simulation, currently "segfaulting", maybe because...

    Grid of emission files not recognized as lat-lon projection, causing a crash

    Dear WRF community, For my MSc thesis research I am running WRF-CHEM with emission files I had to create myself. These emission files have the following naming convention: <wrfchemi_d01_yyyy-mm-dd_HH:MM:SS>. This particular WRF-CHEM simulation covers 24-06-2018 up to 01-01-2018, thus running for...

    Latitudinal shift of Cheyenne's SRTM_3s topography data

    Dear WRF Community, I have successfully run a geogrid program using Cheyenne's SRTM_3s topography data for my 259m resolution simulation. However, while I checked the HGT_M variable using ncview I do see a latitudinal shift (to the north) of topography for SRTM_3s. I then checked the same grids...

    Small HGT error when running geogrid on high-res dataset

    Hello, I downloaded USGS 1/3" topographic data for some simulations I am working on. I was able to stitch together multiple tiles into my own dataset according to WRF guidelines (i.e. the whole 0xxxx-0xxxx.0yyyy-0yyyy naming conventions), and can successfully run geogrid.exe and generate maps...

    Land use data with lower priority unused in geogrid process while using multiple land use data

    Hi All, I am trying to use multiple land use data during the geogrid process. I'm using WRFv4.1(and WPSv4.1) and will be using WRF-UCM(Single Layer UCM) with 3 urban categories(31~33: low-res, high-res, commercial). One of the multiple land use data is what I will call from now on "new data"...

    Will WRF developers update the available static landuse files?

    Hello, I recently attended the WRF/MPAS users' workshop, and more than a few discussions about landuse came up. I'm curious if there is any plan to update the available static geographic datasets that are used in geogrid. I haven't been able to find much documentation about how old these...
