I'm having some problems with the metar2nc decoder.  I've installed

the latest version of the decoder and netcdf-perl, but most of the rawmetar.XXXX.nc files are empty. I've attached the only one that

actually has data in it (just a few lines).  I've also attached one of
the typical log files being generated by metar2nc, and a XXXXXXXX_metar.nc
file referenced by it.  Finally, here is my pqact.conf entry which
activates the decoder:

DDS|IDS ^S[AP].* .... ([0-3][0-9])([0-2][0-9])
        PIPE    decoders/metar2nc decoders/metar.cdl

data/newton/surface/sao

John,

pqact entry should look like this:

#
# metar decoder, creates NetCDF files formated
# data/decoded/yymmddhh_metar.nc
#
# All aviation reports including metar tests
DDS|IDS ^S(A....|P....|XUS8.) .... ([0-3][0-9])
       PIPE    decoders/metar2nc
       etc/metar.cdl
       data/decoded
       (\2:yy)(\2:mm)

I couldn't read your mime attachments.  The rawmetars files are metars
that were not contructed correctly for some reason, so they are saved as
parts. The only reason to save the raws was in case someone really needed
that report. I couldn't read the log or the *.nc file.  I would look at
the decoded reports with ncdump, ie

% ncdump 02051301_metar.nc  | more

The file format should be yymmddhh

Let me know if you still have problem, just the log file info section
should be fine.

Robb...

Any ideas?
