metgrid

Dear all, I am trying to use the MPI-ESM1-2-HR ssp858 and apply the dynamical downscaling. To convert the nc file to intermediate files I am using the python script provided GitHub - lzhenn/cmip6-to-wrfinterm: tools to process cmip6 data to drive wrf. I successfully create the intermediate...

Hi I am running a two-way nested simulation for quite a large area (see namelist.wps attached) and for quite a long simulation (1980-2014). I am now to run metgrid.exe and am curious as to whether there will be any value running metgrid.exe in parallel with mpirun. I hope someone can provide...

Dear all, Please excuse myself since I'm a totally beginner with WRF. I've tried to search for the answer thoroughly but couldn't find any possible solution. My current aim is I'm trying to run WPS for a few years including 1887, 1889, 1930, 1945, 1954, 1971, 1972 with data from 20CR...

I have a problem with my large number of met_em file with date format yyyy-mm-dd_hh_mn_ss while real exe looks for yyyy-mm-dd_hh:mn:ss. How to set namelist.wps to force metgrid.exe to output files like met_em.d03.2012-01-15_03:00:00.nc and not met_em.d03.2012-01-15_03_00_00.nc. Thanks

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...

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...

Hi, I'm trying to WRF to find solar irradiance. I downloaded the data from this site Index of /pub/data/nccf/com/gfs/prod I'm getting error while running Metgrid.exe Processing domain 1 of 1 Processing 2022-11-08_00 FILE ERROR: Error in ext_pkg_write_field...

Hi , I'm getting this error While Metgrid.exe . I'm attaching namelist.wps and metgrid.log for reference Regards Naveen Venkat

Hello, I am trying to complete the hurricane Matthew case from the ARW Online Tutorial. I have gotten a successful run for all steps of the tutorial except using metgrid to process the files, instead having to borrow the data from the webstie. Metgrid seems to be processing the first file...

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...

Hello, I recently planned to study the effect of soil moisture on air temperature, so I wanted to modify the soil moisture in the met_em* files. However, I found out today that there are negative values in the soil moisture (Variable: SM, SM000007, SM007028, SM028100, SM100289), which confuses...

Hi, I would like to use WRF output as input for a new WRF simulation. As I deleted some variables from the output and my new domain has a resolution with a parent_grid_ratio different than 3 and 5, ndown shouldn't be suited to produce the forcings. So I guess the only solution is to use UPP...

Hi all, I have a doubt in the met_em files generated. I'm trying to reproduce the results of the simulation from the article -"Recovery processes in a large offshore wind farm". I'm using WRF 4.4.1 and WPS 4.4 for the current simulation. I have successfully compiled the WRF and WPS with the...

Dear all, I am using the Polar-WRF and its need some other data which are not available in GRIB.So I wrote these data into the intermediate file WPSformat with NCL.It did work and I got intermediate file like:ALBSI:yyyy-mm-dd ICEDEPTH:yyyy-mm-dd However,when I was trying to run metgrid.exe,it...

Hi, I'm using WPS 4.4 and WRF 4.4 version. I'm getting this error when I run metgrid.exe Processing domain 1 of 1 Processing 2022-10-18_00 FILE ERROR: Error in ext_pkg_write_field -------------------------------------------------------------------------- MPI_ABORT was invoked on rank 0 in...

hello, I am trying to run WPS. I've completed the geogrid.exe and ungrib.exe. However, when I try to run metgrid.exe, I got this error: My WRF version is 4.4 so I don't understand why I get this error. is there anyone can help me? thanks!

Hello, I am using WRF4.1 and ERA5. I was wondering how SOILHGT from the ungrib.exe is used in the metgrid.exe/real.exe. Does SOILHGT interact with HGT_M of geo_em files or HGT of wrfinput files? Thanks, Siyu

Dear all, I am using IPSL CMIP5 model to run WPS. However, only times 00,06,12, and 18 can have output after the ./metgrid.exe run. The outputs only have one level of data, that is: BOTTOM-TOP_GRID_DIMENSION = 1 ; The ungrib.log, metgrid.log and the ncdump -h met_em output are attached here...
