Hello,

We've been receiving complaints from some of our internal users that we
have not been receiving ECMWF data (see headers below). 
Since we archive every product with a WMO header that starts with H, and
since we ingest both from our own NOAAPORT system and the IDD, I do not
suspect a data transmission problem (the logs clearly indicate that
there has been no data loss).  Rather, I suspect ECMWF and/or NOAA may
have
changed the headers on some of the products distributed and/or removed
some products from the datastream.  I checked
http://www.nws.noaa.gov/datamgmt/notices.shtml to see if there were any
changes, but could not find any, nor could I find anything useful on the
ECMWF website.  I would like to be able to find some sort of
documentation to support my theory but I'm running out of places to
look.  

Any suggestions?

Thanks,
Brendon

The WMO headers in question are:
