All,

re: Gilbert asked

I just got off a conference call with the NOAA technical contacts for
NOAAPort.  There _was_ a change made this morning by the contractor
that handles the SBN (Raytheon), and that change is negatively impacting
the Unidata NOAAPort ingest code.  The technical contacts should be
teleconferencing with Raytheon right now to see if the changes can
be undone.  If they can not, we will need to make some code modifications
in the NOAAPort ingest code to account for the changes made.

Just so everyone knows:

- the changes being alluded to above were made sometime between
  15:03 and 15:26 UTC this morning

- the changes are affecting more than the IDD NGRID datastream; they
  are also negatively affecting the HDS datastream, but not as badly
  as NGRID

- the data in the NGRID and HDS products are good.  Users decoding
  the products using McIDAS-XCD (like me) should not have noticed
  any problems.

  Sites that have complex patterns for matching product IDs in
  LDM pattern-action files should have noticed that they have
  processed a fraction of the data that would normally be expected
  throughout the day.

- since CONDUIT data do not originate in NOAAPort, they remain
  unaffected.

Cheers,

Tom
