         NCEP AND NWS FTP SERVERS.

NOTE: ALTHOUGH THIS NOTICE FALLS OUTSIDE THE PROVISIONS AND
REQUIREMENTS OF NWSI 10-1805, IT IS BEING TRANSMITTED AS A
COURTESY.

ON APRIL 24 2002 THE NATIONAL CENTERS FOR ENVIRONMENTAL
PREDICTION /NCEP/ AVIATION /AVN/ MODEL WAS RENAMED TO THE GLOBAL
FORECAST SYSTEM /GFS/ 2 MODEL.  AT THIS TIME...THE NAME AVN IS
STILL USED ON OPERATIONAL NWS FILE TRANSFER PROTOCOL /FTP/
SERVERS TO DESCRIBE GFS MODEL DATA SETS.  DURING THE NEXT 6
MONTHS...NCEP WILL WORK ON A PROJECT TO RELABEL ALL NCEP AVN
OUTPUT TO GFS ON OFFICIAL NWS EXTERNAL FTP SERVERS.

THIS PROJECT WILL BE ACCOMPLISHED IN TWO STAGES.  FOR THE FIRST
PHASE OF THIS PROJECT...THE FTP SERVERS WILL BE POPULATED WITH
DATA THAT HAS THE GFS NAME.  THIS WILL BE ACCOMPLISHED BY JUNE 15
2004. THE SECOND PHASE OF THIS PROJECT WILL REMOVE ALL AVN NAMED
PRODUCTS...LEAVING ONLY THE GFS NAMED PRODUCTS BEHIND.  THIS
SECOND PHASE WILL BE ACCOMPLISHED NO EARLIER THAN JANUARY 1
2005. THE EXACT DATE OF THIS CHANGE WILL BE PUBLISHED AS SOON AS
IT IS KNOWN.

USERS SHOULD BEGIN TO MIGRATE THEIR PROCESSING TO POINT TO THE
GFS NAMED DATA SETS AS SOON AS THEY BECOME AVAILABLE.  THIS WILL
ALLOW FOR A TRANSPARENT CHANGE TO OCCUR WHEN THE AVN NAMED DATA
SETS ARE REMOVED.

THIS CHANGE AFFECTS THE DATA ON THE FOLLOWING TWO SERVERS:

THE OFFICIAL NWS SERVER AT /USE LOWER CASE LETTERS/:

  FTP://TGFTP.NWS.NOAA.GOV/

AND THE NCEP FTP SERVER AT /USE LOWER CASE LETTERS/:

  FTP://FTPPRD.NCEP.NOAA.GOV/PUB/DATA/NCCF/COM/
