geogrid

I’m currently running Noah-MP + BEP/BEM (sf_urban_physics = 3) simulations using HRLDAS/WRF and working with CGLC_MODIS_LCZ_global data for urban classification. For a sensitivity experiment, I want to test the impact of ±20 % vegetation fraction changes (e.g., to simulate adding or removing...

Hello, I am trying to apply a custom landuse dataset (EGIS Landuse for Korea) to WPS geogrid. The dataset was converted into BIL tiles (200×200 pixels each, 30 arc-sec resolution), and I created an index file as follows: type=categorical category_min=1 category_max=21 projection=regular_ll...

Hi everyone, I have geo_em files generated by WPSv4.4 that include urban building information. Using Python scripts, I converted the "LU_INDEX" and "LANDUSEF" in the geo_em files to make them compatible with WPSv4.5. After running the full workflow in WRFv4.5.2, the results suggest that building...

Hello guys, I am trying to make a simulation for my studies. I was told that " geog_data_res = 'modis_30s+noah'" is recommended for my simulation. I have a coarser domain of 15km and a finer domain of 5km. But I got this error: "Parsed 50 entries in GEOGRID.TBLProcessing domain 1 of 2ERROR...

Hi, I am beginner using wrf. Is it possible to suggest how to setup GEOGRID.TBL Table for noah_mp opt_run=5 ?

Hi All, I'm trying to use Gao's 2020 SSP5 urban fraction data (https://dataverse.harvard.edu/file.xhtml?persistentId=doi:10.7910/DVN/85PJ1D/N3Y1JC&version=1.0) in WRF. I followed the User Guide to convert TIFF to BIL format and make WRF-ready files (Chapter 3: WRF Standard Initialization), but...

I have an appplication that is very performance-critical and therefore I would like to run especially metgrid with MPI. However, I get messages of the form ERROR: Error in ext_pkg_open_for_write_begin. I am using WPS 4.6.0 and I run it with mpirun -np 4 ./geogrid.exe. I compiled with the MPI...

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...
