Hello, I'm currently trying to use custom SRTM-based topography data in WPS (v4.x), but encountering issues where terrain height (HGT_M) in the generated geo_em.d0*.nc files appears flat or incorrect. Process: I downloaded SRTM data using QGIS and exported it as GeoTIFF (.tif). I used GDAL to...

I am trying to use a custom EGIS Land Use dataset for WRF-UCM by converting it into a binary (BIL) file. However, after running geogrid.exe, the generated geo_em.d03.nc file does not reflect my custom dataset, and LU_INDEX remains at 17 across the entire domain. Steps I Followed: Converted an...

This is my first time asking on a forum, and I am a new WRF user. I'm running PolarWRF in the Antarctic region. But there is something wrong with my experiment. When running geogrid.exe for the first time, an error occurred: Could not open ...../WPS_GEOG/ramp1km/index. I downloaded the...

Hi, I'm working on customizing Landuse data for WRF and encountered an issue when running real.exe. The model stops with the error message: grid%tsk unreasonable I suspect the issue is related to Landuse preprocessing. Here are the steps I took to integrate the land cover data: Custom...

Hello, I want to perform a real case simulation in which I have one nested domain. The namelist.wps and the GEOGRID.TBL I used are in the zip folder attached here (GEOGRID.TBL is the default one). Geogrid program successfully completes and parent domain looks fine, but when I check the...

Hi I am running ./geogrid.exe and ./ungrib.exe command on supercomputer but it giving me error that /geogrid.exe: error while loading shared libraries: libnetcdff.so.7: cannot open shared object file: No such file or directory and /usr/mathlib/libpng/lib/libpng15.so.15: version `PNG15_0'...

Hi! I am confusing with the land use category mapping with the Geotiff data from jaxa. My original Geotiff data is from here. https://www.eorc.jaxa.jp/ALOS/en/dataset/lulc/lulc_v2312_e.htm (Coordinate system and category numbers are listed in this page. Notice the category order is not followed...

Hello, I am getting this error when i try to run ./gegrid.exe At line 140 of file gridinfo_module.f90 (unit = 10, file = 'namelist.wps') Fortran runtime error: Invalid string input in item 7 Error termination. Backtrace: #0 0x7f3e77be3e59 in ??? #1 0x7f3e77be4a71 in ??? #2 0x7f3e77be56dc...

I was using NUDAPT dataset provided on the WPS_GEOG data website for running BEPBEM WRF simulations. I later developed my own set of UCPs required from the explicit building footprints and building heights data we had. I followed some of the older documentations of NUDAPT...

Dear all, is there a guideline or "best practices manual" for choosing the values of truelat1 and truelat2 when using an LCC (Lambert Conformal Conic) coordinate system? For context, I am working with four nested domains with resolutions of 27 km, 9 km, 3 km, and 1 km. The finest domain...

Hi all, There have a few posts on this issue, but I'm in the unusual position that it seems to have been triggered by changing the land-cover specification. I've been using the same namelist.wps and namelist.input, but between yesterday and today I modified the GEOGRID.TBL file to match...

I am working on a project that is running multiple high-resolution (3 km) simulations of events spanning the entire 20-th and 21-st centuries. We have completed all but one of our events after 1940 (~25 events total) using ERA5 as our forcing dataset with a 9-3 km two-domain nesting setup. We...

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...

Hello! I'm running WRF-Fire for the first time so I'm following the tutorials on youtube. I'm stuck at the geogrid step because I see that geogrid runs successfully but does not processes NFUEL_CAT and ZSF. I followed carefully the instructions of the tutorial so I can't understand where is the...

Good morning from Chile. I would like your assistance with this; using WPS4.1; I'm a computer specialist, and not an Earth-science minor/major, so I'm a bit in the dark regarding this. We are trying ro create a set of nested domains for Antarctic continent (Antarctica/Antarctica); I'm also...

Hello everyone, I'm currently encountering an issue while running WRF version 4.5. The error message I receive is as follows: -------------- FATAL CALLED --------------- FATAL CALLED FROM FILE: <stdin> LINE: 2419 Warning: too many input landuse types I replaced the original land use data in...

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...

I am trying to ingest city specific urban canopy parameters that I developed using buildings heights and footprints data. The UCPs I built were: 1) Mean Building Height, 2) Distribution of building heights for 5m bins, 3) Area weighted mean building height, 4) Standard deviation of building...

Dear users, I am getting an error when trying to execute ./metgrid.exe. The error is ERROR: Couldn't open file ./geo_em.d01.nc for input. Version Details : WPS-4.5 WRF-4.5.2 Input data : ds083.2 List of attachments: namelist.wps Vtable geogrid.log metgrid.log ungrib.log Please suggest...

I am not sure why, but when I try using the above dataset and run geogrid.exe the result is pure MODIS- no LCZ categories at all. The paper on the dataset says that the GEOGRID.TBL entry needs to have higher priority than default MODIS, but if the priority is different in the GEOGRID.TBL.ARW_LCZ...
