SERVERS,(tgftp andptgftp).

BOTH DATA SETS WILL CONTAIN THE GRIB BULLETINS KNOWN AS THE AVN
GLOBAL OCTANTS ALSO SOMETIMES REFERRED TO AS WAFS GRIDS.  ONE DATA SET
WILL HAVE BE IN THE FORMAT AND HAVE THE PATH AND FILE NAMES ANNOUNCED
YESTERDAY.

THE OTHER DATA SET WILL HAVE FILES CONTAINING THE AVN GLOBAL
OCTANTS WITH THE PREVIOUS NAMES AND DATA CONTENT AS THEY WERE PREVIOUSLY
WRITTEN ON tgsv1(140.90.88.142).  THIS DATE SET WILL BE WRITTEN  TO THE
ROOT DIRECTORY OF THE FTP SERVERS.  THIS MIRRORS WHAT WAS PREVIOUSLY
WRITTEN ON tgsv1 (140.90.88.142).  THIS SECOND DATA SET WILL BE LEFT IN
PLACE UNTILMARCH 1, 2003 ONLY.  ONLY THE AVN GLOBAL OCTANTS WILL BE
WRITTEN.  FOR USERS WHO WERE PREVIOUSLY GETTING THE AVN GLOBAL OCTANTS
FILES FROM TGSV1, THE ONLY CHANGE THEY WILL NEED TO MAKE IS THE ADDRESS
USED TO PULL THE FILES FROM.

THE FULL URLS FOR tgftp and ptgftp, WHICH ARE BOTH CLUSTERS OF
SERVERS, ARE:

       ftp://tgftp.nws.noaa.gov/

       ftp://ptgftp.nws.noaa.gov/

tgftp IS OPEN TO THE INTERNET AND SHOULD BE USED BY MOST PEOPLE.
ptgftp IS A PRIVATE URL AND WILL BE USED BY PEOPLE WHO HAVE BEEN GIVEN
ACCESS TO THIS SYSTEM.

BOTH, DATA SETS WILL BE AVAILABLE IN PARALLEL TO FACILITATE MOVING
OFF  THE OLD  AND TEMPORARY FORMAT.  IT IS STRONGLY RECOMMENDED THIS
MIGRATION BE PURSUED AGGRESSIVELY.  IT IS ALSO STRONGLY RECOMMENDED THAT
