Weird results after converting netcdf to WPS intermediate files

[Liliputian_123]

Dear WRF users,

I converted OISST netcdf to grib format.

I am using the script from the WRF directory.
https://www2.mmm.ucar.edu/wrf/users/special_code.html

netcdf-to-intermediate.f

When I compiled the code,
I removed this line:

integer, intrinsic :: iargc

and added this line:

open(11, file=filename, form='unformatted',convert='big_endian')

Then, it successfully compiled.

The output is read perfectly fine when I used rd_intermediate.exe.

When I tried using plotfmt.ncl, the code stops with the following error:

 SUCCESSFUL COMPLETION OF PROGRAM RD_INTERMEDIATE

But when I tried the plotfmt.ncl in utilities, I get the following error:

At line 32 of file plotfmt_rdhead.f90 (unit = 10, file = 'SST:2021-07-01_00')
Fortran runtime error: I/O past end of record on unformatted file

I tried converting the file to netcdf and also used the plotfmt_nc.ncl but the results are weird.

I am attaching the output image here and the converted file.

any suggestions how to solve this?
Just remove the .txt extension in the SST file.

Are you having trouble running metgrid with this SST file? If the problem is just with plotting the file, you should post it in the NCL section of the forum, since the plotting utility is an NCL-specific script.

Hi Kwerner,

The problem is not the plotting.
I think it's the fortran converter code.
It did not successfully compiled.

Is there anyone here who was able to successfully compile this script (the nercdf to intermediate converter)?

I'll appreciate any help on this.

Hi,
Did you try to run metgrid using the SST file you created? The ncview image you sent looks normal to me, and I was able to run through metgrid with your file, and see SST, which has reasonable values.
