Re: NCL error when runing WRFSI GUI

Hi Alex,

I m not familiar with the WRFSI model and how it uses NCAR Graphics,
or where it tries to write the NCGM files. The NCL_COMMAND environment
variable is not one that we recognize, so this must be something that
WRFSI depends on.

Having said this, there may be other reasons why the avc.d01.ncgm file
did not get created. For one, maybe the directory path is wrong, or
not writable by you. Or, if the directory is close to 100% full, it
may not allow you to write more files there. The other possibility is
that there is something wrong with the avc.ncl script, and it couldn't
be fully executed.

The error message "WARNING: avc.ncl FAILED TO GENERATE NCGM FILE" is
coming from the WRFSI package, I believe, and not from NCL or NCAR
Graphics. You may need to look at the documentation or code for WRFSI
to see what could be the possible causes of this error message.

This should give you a few places to start looking for the problem.
Let me know if you think we can be of more help somehow.
