Dear staff, I get "Error in ext_pkg_write_field" when I run metgrid.exe
"ERROR: Error in ext_pkg_write_field
Abort(40076608) on node 0 (rank 0 in comm 0): application called MPI_Abort(MPI_COMM_WORLD, 40076608) - process 0", indicating successful execution of both geogri.exe and ungrib.exe, I had the same problem with both WRFV3.7 and 4.4 and only produced met_em files for the d01 grid. Here is my namelist.wps file1739502974841.png

Hi,
This error "ext_pkg_write_field" typically indicates that there is some surface data missing, and you should check that all your 3d meteorological fields include surface-level data. However, it's interesting that it works okay for d01, and then stops when it reaches d02. Regardless, can you check your data to make sure?

Setting that issue aside, I notice that your grid-spacing (dx/dy) are set to a very high resolution for the parent domain (900 m). What is the resolution of your input meteorological data? We recommend that the ratio between the resolution of the input data is no more than about 5:1 to that of the parent domain. That is likely not related to your current issue, but if it's much larger than 5:1, you will likely run into problems when running real and/or wrf. If your goal is to resolve the 100 m domain, you probably need to add additional domains around the current parent to make sure the difference in grid spacing between the outer-most parent and input data is no more than 5:1. If it is, indeed, larger, can you make those modifications and try running again and let me know what happens? Like I said, I don't think this is related to your error, but it should be fixed before moving forward. Will you also please let me know what type of input data you're using?

Another note: You have the namelist parameter "io_form_geogrid" set in the &geogrid namelist record, but it actually belongs in the &share record.
 
Thank you very much for your reply, but now I have encountered a new problem. When WPS and WRF real run successfully, the error in the figure repeatedly occurs when executing./wrf.

Although I reduced time_step to 4dx, 3dx, etc., the same error still occurs. This error occurred at 30 minutes of running. Here are my rsl.error.0000 and namelist.input files.
I tried to run the program with fnl data and ERA5 data, but I had the same problem with./wrf.exe, all of which worked successfully. I would appreciate your prompt reply.

Dear kwerner, I try to download the GFS data on the web site NCAR RDA Dataset d084001 to simulate but still received the same error, And I get the same error every time I run wrf.exe until 30 minutes (although I also modified time_step to try 4dx and 3dx). Attached below is my namelist.wps file.

Hi,
I'm glad to hear you were able to get past your initial issue. Since this is a different issue than the one orignally posted here, please start a new thread for this problem. Keeping each post focused on one issue makes the forum easier to read and search in the future. Thanks!
