    Using geogrid.exe for Antarctica (Antartica), help with DEM data

    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...

    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...

    Urban canopy parameters ingestion into WPS/ WRF

    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...

    How do I get the LCZ part of CGLC_MODIS_LCZ_global to work?

    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...

    A question about GEOGRID

    Hello I am building a grid to be run by WRFHYDRO. I manage to prorperly select the domain (~10km * 20 km) and the resolution (500 m) when I look at the produced coordinates (long_M and LAT_M) I see that the intervals are not exactly equal and there is some kind of periodicity in the cell size...

    geogrid.exe stops without error with my own binary file

    Hi, all I'm trying to replace the MODIS land cover data with the high resolution data which has shape format. I changed this file with QGIS and made binary file with write_geogrid.c code which is in the WPS/geogrid/src directory. I moved this binary file into the GEOG directory to run geogrid. I...

    (Resolved) Why high-resolution terrain data does not match actual altitude?

    Hi, I have now made a three-layer nested domains simulation with a ratio of 1:3:3, the grid accuracy of the finest nested area is 1km, and then the longitude and latitude of my target site is very close to one of the grid points in the 3rd nested domain. The distance is only about ten meters...

    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...
