WRF output files

[Kaishini Sabapathee]

Having an issue with wrf output files. For each partial simulation only the first output file is being saved fully.The subsequent files have only partial data. Thank you for your help.
Namelist files are attached.

Would you please clarify the issue? By saying "The subsequent files have only partial data", do you mean not all variables are saved, or not all times of output files are produced?

Not all variables are saved

Please save the output of the command "ncdump -h" for the first wrfout file and one wrfout after the first time of output. I would like to know what variables are missing.

Attached are the files for the first output file(wrfout_d02_2024-01-10_00:00:00 (83.4mb) )and 2 subsequent problematic file( wrfout_d02_2024-01-10_01:00:00, wrfout_d02_2024-01-10_13:00:00).

The subsequent files(e.g wrfout_d02_2024-01-10_01:00:00 (18.1mb), wrfout_d02_2024-01-10_13:00:00(10.8mb) and others) vary in size.The issues persist across different subsequent files. The smaller files appear to have missing variables or incomplete data.The first file(wrfout_d02_2024-01-10_12:00:00)seems complete and larger in size compared to the others.

All these files you posted have the size of around 45kb and they are not in netCDf format. I wonder what is going on?

 

[Ming Chen]

One issue about the file output is that, you set

frames_per_outfile = 1000, 1000, 1000,

I would suggest that you change it to

frames_per_outfile = 1, 1, 1,

Please rerun this case with the above option and let me know whether you still have the issue.

Files sent earlier: The files i attached were metadata outputs generated using the ncdump -h command, which contains information about the netCDF files. This is why their size is around 45kb and they are not the full netCDF files.

The actual netCDF data files are much larger. For example, the first file (wrfout_d02_2024-01-10_00:00:00 is 83.4mb, while subsequent problematic files like wrfout_d02_2024-01-10_01:00:00 , and wrfout_d02_2024-01-10_13:00:00 are smaller (18.1mb, 10.8mb respectively). These smaller files seem to have missing variables.

Thank you for your feedback regarding the frames_per_outfile setting. I wanted to clarify that in my current namelist.input file, I have already set: frames_per_outfile = 1, 1,

This setting is consistent with your suggestion. Given this, I'm wondering if there might be another configuration or aspect related to the file output that I should check or adjust?

Thank you for your help.
