1.  Updates from Climate and Forecast convention 1.4 to 1.6 and OceanSITES-1.2 to OceanSITES-1.3 conventions;
2.  A subset of existing TAO netCDF data files in the OceanSITES GDACs are replaced by the new data files. The files being replaced are listed as follow:
OS*_R_AIRT.nc, OS*_R_ATMS.nc, OS*_R_FLUX.nc, OS*_R_OCUR.nc, OS*_R_PRES.nc, OS*_R_PSAL.nc, OS*_R_PSTN.nc, OS*_R_TEMP.nc, OS*_R_WIND.nc;
3.  All existing historical TAO legacy data files in earlier formats in the NDBC THREDDS Data Server are replaced by the new data files.

The TAO data files replaced are as follows:
OceanSITES GDACs: ftp://data.ndbc.noaa.gov/data/oceansites/
NDBC THREDDS Data Server: http://dods.ndbc.noaa.gov/thredds/catalog/oceansites/catalog.html
Legacy data files: http://dods.ndbc.noaa.gov/thredds/catalog/oceansites-tao/catalog.html
These files will be available and posted on NDBC public website until 11 May 2015.


Based upon the above change NDBC recommends that all users of TAO NetCDF data review the new data files at their earliest convenience for easy migration of their data processing.

Distribution of Tropical Atmosphere Ocean (TAO) data via BUFR
Correction - National Data Buoy Center (NDBC), Distribution of Tropical Atmosphere Ocean (TAO), data via BUFR under ISSF08 KWNB and ISSG08 KWNB headers
Notification from RTH Washington
The NWS NDBC will being dissemination of TAO data in BUFR format under the WMO headings collective of IOBF08 KWNB and IOBG08 KWNB. The current ASCII formatted messages in FM18 BUOY will continue to be distributed under the SSVX08 KWNB header.

IOBF08 KWNB will be used for all TAO stations with a nominal position east of 180.
IOBG08 KWNB will be used for all TAO stations with a nominal position on or west of 180.

All users currently receiving the SSVX08 KWNB headers have automatically been added to the distribution of IOBF08 KWNB and IOBG08 KWNB. Therefore effective 2 March 2015 data will be received in both FM18 BUOY and BUFR format.

Users with automatic decoders should reprogram their systems now to recognize the new bulletin headers and the BUFR format for these observations. At present time NDBC has no plans to discontinue our TAO distribution in the FM18 BUOY format.
