THE IMPLEMENTATION BELOW IS RESCHEDULED FOR 1400 UTC
OCTOBER 20. THIS POSTPONEMENT IS FOR OPERATIONAL REASONS.
THE NWS SYSTEMS OPERATIONS CENTER CHANGE NOTICES WEB
PAGE HAS BEEN UPDATED.
ON OR ABOUT OCTOBER 1 1998 A SOFTWARE IMPLEMENTATION WITH
SEVERAL CHANGES WILL TAKE PLACE CONCERNING THE DISTRIBUTION
OF MOORED BUOY AND C-MAN OBSERVATIONS FROM STATIONS
OPERATED BY THE NATIONAL DATA BUOY CENTER /NDBC/. ONE OF
THE CHANGES WILL REDUCE THE DELAY IN TRANSMITTING THE
OBSERVATIONS TO ALL USERS. ANOTHER CHANGE AFFECTS HOW
USERS WILL OBTAIN SPECTRAL WAVE OBSERVATIONS. OTHER
CHANGES ARE RELATIVELY MINOR. A BRIEF DESCRIPTION OF SOME
OF THE CHANGES IS GIVEN BELOW.
NDBC WILL RELEASE COMMUNICATIONS HEADINGS CONTAINING
GROUPS OF MOORED BUOY AND C-MAN OBSERVATIONS EVERY 5
MINUTES INSTEAD OF 4 TIMES AN HOUR.
NOTE THAT THIS WILL NOT INCREASE THE NUMBER OF NDBC
OBSERVATIONS TRANSMITTED MOST STATIONS STILL TRANSMIT
ONE OBSERVATION PER HOUR BUT THIS CHANGE WILL IMPROVE
THE TIMELINESS OF DATA. USERS MAY NEED TO INCREASE THE
NUMBER OF PRODUCT VERSIONS RETAINED IN THEIR AFOS OR
METEOROLOGICAL WORKSTATIONS TO MAINTAIN THE SAME TIME
HISTORY OF PREVIOUS OBSERVATIONS.
THREE-HOURLY AFOS TRANSMISSIONS OF SPECTRAL WAVE DATA
UNDER PIL HEADINGS NMCBSOPO- NMCBSOP7 WILL CEASE. THE
WMO HEADINGS OF THESE PRODUCTS ARE
SXVX30 KWBC - SXVX39 KWBC. MORE DETAILED SPECTRAL WAVE
OBSERVATIONS ARE TRANSMITTED MORE FREQUENTLY IN
WMO FM-65 WAVEOB CODE. THESE ARE AVAILABLE ON THE FRAME
RELAY NETWORK FOR NWS FIELD OFFICES AND THROUGH
THE NWSTG FOR OTHER USERS. PC SOFTWARE TO DECODE AND PLOT
THESE OBSERVATIONS WAS DEVELOPED BY THE WFO IN SEATTLE
WASHINGTON AND IS AVAILABLE FROM THE SSD IN THE WESTERN
REGION. THE COMMUNICATIONS HEADINGS FOR THE FM-65
MESSAGES ARE SXVX40 - SXVX49 KWBC AND SXVX60 - SXVX69 KWBC.
FM-65 WAVEOB MESSAGES WILL BE RELEASED TWICE AN HOUR FOR
STATIONS REPORTING TWICE AN HOUR. THESE WERE PREVIOUSLY
