[Met_help] Re: Data interface about met program?

[John Halley Gotway]

Sorry to hear about the PGI compilers.  If you'd like to send the Makefile
and compilation log file, I could take a look and see if there's anything
obviously wrong.

What I mean is, when you build MET using a command like...
make -f Makefile_pgi >& make_met.log
... please send me a copy of the "Makefile_pgi" that you're using and a
copy of the "make_met.log" logfile.

Regarding the issue of using point observations in ASCII format, several
users are encountering the same obstacle.  For the next release of MET,
I'd like to add a utility that will convert formatted ASCII point
observations into the NetCDF format that MET is expecting.

However, that release won't be ready for a couple of months I'd say.  In
the meantime, I need to write up some instructions describing what the
NetCDF point observations should look like for those users who would like
to reformat their observations into NetCDF themselves.

So I'll work on those basic instructions tomorrow, post that info to the
MET website, and let you know when it's available for you to take a look
at.

Thanks,
John
