THIS MESSAGE PROVIDES NOTICE THAT THE NWS NATIONAL DATA BUOY CENTER
/NDBC/ WILL DISSEMINATE TAO RECAP BUOY DATA UNDER THE /WMO/ HEADINGS
/COLLECTIVE OF IOBF08 KWNB.

THE MAJOR DIFFERENCE WITH THIS TAO RECAP BUOY WILL BE THE FREQUENCY
OF THE REPORTS.  THE TOP SIDE /MET DATA/ WILL BE TRANSMITTED EVERY
10 MINUTES...WHILE THE BOTTOM SIDE /OCEANOGRAPHIC DATA/ WILL BE
TRANSMITTED HOURLY.  HOWEVER...THE HOURLY TRANSMISSION WILL INCLUDE
ALL THE 10 MINUTE OBSERVATION DATA.

IN ADDITION...STARTING WITH THE TAO RECAP BUOYS NDBC WILL BE PHASING
OUT THE TAC DISTRIBUTION OF TAO DATA.  THEREFORE...DATA FROM THIS
BUOY WILL ONLY TRANSMIT DATA USING BUFR FORMAT AND IT WILL NO LONGER
BE TRANSMITTED UNDER THE TAC HEADER SSVX08 KWNB ON THE EFFECTIVE
DATE.

THE TAO RECAP BUOY WILL ESSENTIALLY TRANSMIT THE SAME DATA TYPES AS
THE CURRENT TAO REFRESH SYSTEM THAT IT IS REPLACING.

THE PRIMARY PURPOSE OF THIS NOTICE IS TO MAKE USERS AWARE OF THE
INCREASED REPORTING FREQUENCY OF THIS STATION AND THAT DATA FOR THIS
STATION IS GOING TO NO LONGER BE DISTRIBUTED ON THE TAC HEADER.  NO
ACTION SHOULD BE REQUIRED FROM THE END USER PROVIDED THE TAO BUFR
DATA IS BEING PROCESSED VICE THE TAC DATA.

NOTE...ADDITIONAL TAO RECAP BUOYS WILL BE DEPLOYED IN FY2024.
