    A bug in WPS-V4.5 about ICON-Global data processing

    Hello, WPS development team, @weiwangncar @grafmi @WQadam There is a bug in WPS-V4.5 about ICON-Global data processing when the ICON-Global data was ungrib. Although the ICON product specification(https://www.dwd.de/DWD/forschung/nwv/fepub/icon_database_main.pdf) states that ICON-global soil...

    USGS 30 ARC SECONDS LULC DATA DOWNLOAD

    Good day dear colleagues, Please I would like to know if the Global Land Cover Characteristics - GLCC data (GLCCGBE20, with Geographic projection) on earthexplorer.usgs.com is the same as the usgs_30s data in WPS. If it is not, can anyone send a link to where it can be downloaded from? Thank...

    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...

    ERA5 surface data not found in WPS

    Hello, I have a problem running WPS with ERA5 data. I have downloaded 2 grib files, one for pressure levels (all pressure levels) and the other one for single level data (all variables ecept precipitation type, K index and total totals index). But it seems like metgrid doesn't recognise surface...

    use ERA5 data in WPS

    Hello I have seen a pdf about using ERA5 data in the WRF model. In that instruction, the author told that we need to download two kinds of data (Pressure level and surface analysis) as you know, there are a lot of parameters in both of them. due to the limitation in processing, it is important...

    New "greenfrac_fpar" tiff for binary WRF

    Hello everybody! I created a new climatology for "greenfrac_fpar" based on GLASS_MODIS products in tiff format, one file for each month. I merged the files into one file with separate bands in QGIS in tiff format. But when I went to convert the new file using this link: GitHub -...

    Can WRF output data be used for Input data on smaller domain

    I have a 4km 120hr WRF run that is created in 5hrs. But when I nest in a 1km grid it increases the time dramatically to finish the run. So my question is can I use the output from the 4km 120hr run as initial data for a new wrf run at 1km? I don't see a vtable in ungrib for WRF on ARGWRF. So...

    ungrib.exe w/ Intel compilers doesn't write "FILE" (Possible solution)

    For some reason when using Intel Compilers it is defaulting the output file name to "PFILE" instead of "FILE" This then causes all the following commands to break because it is looking for a file that isn't there. Environment is the same as this post for a similar error...

    I want to read SST using ghrsst

    I recently noticed that NCEP's SST data is no longer available. So I'm thinking of using this site (GitHub - bbrashers/WPS-ghrsst-to-intermediate: Converts JPL PODAAC GHRSST netCDF files to WPS Intermediate version 5 files) to incorporate SST, but I'm a beginner and I don't know what to do or...

    How can I convert a SST .dods data file into grib2 file to be used in WPS?

    Hi there, I'm trying to add SST data into my WRF model of the Greater Toronto Area. I've downloaded some data from OSTIA, but the only options to download the data were ASCII and binary (.dods). Since I need to use this data in WPS, I was trying to format the data as a grib2 file using CDO, but...

    Finding SST data for WRF

    Hi there, I am completely new to using SST data and I'm not sure where to start. I think I understand what I'm supposed to do once I actually have the data, but I'm not sure where to get it, especially in a form where I can use ungrib on it. I'm currently modelling temperatures in Toronto, but...
