19990407: NIDS on NOAAPORT

Dan,

I was not sure about whose NOAAPort feed you were refering to- 
Are you still talking about the university feed from us, or your own
Unysis system? 

Anyhow, here is the NWS notice regarding all WMO headers with 97 in them.
I presume this includes SDUS97!

NOXX47 KWBC 071530
ALERT      ALERT      ALERT      ALERT      ALERT

NOTICE ABOUT UNOFFICIAL NWS PRODUCTS CONTAINING 97 IN WMO HEADING

AS DEPLOYMENT AND TESTING OF THE NATIONAL WEATHER SERVICE
ADVANCED WEATHER INTERACTIVE PROCESSING SYSTEM /AWIPS/ CONTINUES
THERE ARE A GROWING NUMBER OF PRODUCTS WITH THE WMO HEADING
FORMAT TTAA97 CCCC BEING TRANSMITTED ON THE AWIPS/NOAAPORT
DATASTREAM.  THESE PRODUCTS WITH 97 IN THE WMO HEADING ARE
UNOFFICIAL NATIONAL WEATHER SERVICE TEST PRODUCTS FROM
UNCOMMISSIONED SYSTEMS AND ARE NOT /REPEAT NOT/ TO BE USED FOR
ANY OPERATIONAL PURPOSE.  THESE PRODUCTS OFTEN DUPLICATE OR ARE
SIMILAR TO OTHER OFFICIAL PRODUCTS WHICH DO NOT CONTAIN 97 IN
THE WMO HEADING.  ONLY OFFICIAL PRODUCTS WHICH DO NOT CONTAIN
97 IN THE WMO HEADING SHOULD BE USED OPERATIONALLY.  PLEASE DO
NOT REDISTRIBUTE THESE PRODUCTS OR POST THEM TO THE INTERNET.
NATIONAL WEATHER SERVICE IS TAKING STEPS TO MINIMIZE THE
AVAILABILITY OF THESE PRODUCTS WHERE FEASIBLE.  IF YOU HAVE ANY
QUESTIONS REGARDING THESE PRODUCTS PLEASE CONTACT NATIONAL
WEATHER SERVICE TECH CONTROL AT 301-713-0902.

I assume any trickle of products out under the '97 headings are
test products only and can be really screwed up.

The routing of the NWSTG products onto theIDD from SSEC's ingestor
places binary products onto the HRS stream- as a FOS-like product.
Glenn is working on a new LDM release that will use the NOAAport header 
rather than the fabricated FOS header since many products like you
are refering to were never intended for the FOS feed, and the
naming convention of FOS is limiting. A revised name space using the
NOAAport information, including AFOS pils etc is under development.
