[Met_help] Question on pb2nc to create daily netcdf OBS files

[John Halley Gotway]

Jonathan,

Yes, there is an easy way of doing that in METv1.1.

Use the "-pbfile" command line option for PB2NC to pass it multiple PrepBufr files.  It should write all the observations to a single NetCDF file.

I haven't used this option much myself, so I'd be interested to find out how it works for you.
