[Met_help] Running point stat

Kemal,

Thank you for sending such a detailed set of files to help me troubleshoot
the issue.  I'm taking a look at it now and will get back to you soon.

In the meantime, I actually have a question for you.  The same day I
received your MET-Help email, I also received an email from another user
who is trying to verify MM5 data.  He's wondering if there are any tools
available for converting MM5 output into a GRIB format that MET could
read.

You mentioned in your email that you converted MM5 data from sigma levels
to pressure levels and wrote your output in GRIB.  Can you tell me how you
went about doing that?  Did you write code yourself or use any existing
tools?  I haven't worked with MM5 data in the past, so I'm hoping you
might have some advice to offer that I could pass along to this other
user.

Thanks,
John Halley Gotway
