An Excel file, regularly updated, tries to list the platform networks that report their observations in BUFR. Information about the template which is used, the TTAAii CCCC headers and some remarks and/or plans are provided for each network.
Conventional VOS ships
Conventional VOS observations are sent ashore through different way.
...
SEAS and E-SURFMAR raw data are converted in FM13 SHIP and FM94 BUFR (information to be checked with regards to SEAS). A few metadata, such as the level of the different main sensors as well as the type of the station are added in BUFR messages to E-SURFMAR observation data prior to their transmission onto the GTS.
BUFR template used for ship data is presently TM308009 (B/C10). It should be replaced by TM308014 (not yet validated) on next year.
Shipborne Automated Weather Stations (S-AWS)
In general, S-AWS send their observations ashore thanks to their own transmitter. This latter may be Inmarsat-C, Iridium SBD, Meteosat DCP, Argos... Data may be raw (binary or alphanumeric) or FM13 SHIP messages (in the case of Meteosat DCPs). FM13 SHIP messages are forwarded onto the GTS as they are and possibly converted in BUFR without any metadata added. Raw data from many European S-AWS (E-SURFMAR dataformat #100) are converted in both WMO codes. Metadata In case of BUFR, metadata are added to observation data prior to the GTS transmission. BUFR templates are the same than those for conventional VOS.
Drifting buoys
For more than 30 years, drifting buoys had been sending their observations ashore thanks to the Argos system, exclusively. Argos data are processed by CLS in Toulouse (France) and in Largo (USA). For many years, data are sent onto the GTS in FM18 BUOY and FM94 BUFR (unvalidated template), in parallel.
Since 2008, Iridium Short Burst Data (SBD) is more and more used for the transmission of drifting buoy data ashore. Several centres are processing the raw data in order to send them onto the GTS in FM18 BUOY. Out of them, some are transmitted in FM94 BUFR (unvalidated template), in parallel.
Although never validated by WMO, a template has been widely used for many years. It should be now replaced by TM315009 recently validated.
