NOVEMBER 2019 .
- 2019/11/28 - Announcement of cessation of TAC transmission of SHIP reports by Météo-France on 14 January 2020.
...
AUGUST 2016 .
- 2016/08/26 - Announcement - A survey on the observations carried out on the 6th of August, showed that (see details in the corresponding pages):
- 99.5% of the drifting buoys report in BUFR with template TM315009 (against 83% that still report in FM18) => migration almost ended;
- 83% of the VOS (manned or automated) report in BUFR with template TM308009;
- only 28% of the moored buoys report in BUFR with the right template (TM315008).

JULY 2016 .
- 2016/07/07 - Announcement - Following a request from Met Office, Meteo-France and CLS agree to postpone again the end of the distribution of FM18 BUOY data. The new deadline is now the 1st of November 2016.
...
MAY 2016 .
- 2016/05/26 - Announcement - A map, drawn by ECMWF, that shows the availability of buoy reports, was published on the drifting buoy page. During the coming months, more and more buoys will only report in BUFR onto the GTS and most of the FM18 (TAC) data will disappear on the 1st of September.
- 2016/05/24 - Problem fixed - Joubeh no longer transmits FM18 messages for buoys that are fitted with a 7-digit WMO ID not convertible in a 5-digit one.
- 2016/05/12 - Problem - Since this date, five buoys (WMO 4401601-4401604) have their data sent by Joubeh onto the GTS (CWAO) in FM18 BUOY format with wrong IDs (WMO 44601-44604). This leads to have duplicates in databanks: the same data are sent with two different identifiers which are not equivalent. In addition, one of these IDs (WMO 44604) is already used by an active E-SURFMAR drifting buoy => the data of two different buoys are sent onto the GTS with the same identifier. Buoys 4401601-4401604 should not report in FM18.

APRIL 2016 .
- 2016/04/26 - Problem fixed - Since today, all BUFR bulletins generated by CLS America (IOBX06 KARS most especially) contain a single message. The migration to BUFR (with template 315009) for drifting buoys should be considered as being complete . Only 4 buoys managed by JMA still report their data according to the never validated WMO template.
- 2016/04/25 - Announcement - Since today, SIO has been producing BUFR messages for drifting buoys with template TM315009. About 100 buoys are concerned. GTS header is IOBX02 KWBC. The transmission of data with the never-validated template (under header IOBX01 KWBC will stop soon. After this event, only JMA still transmits drifting buoy data through the never-validated WMO template but 4 buoys are only concerned.
- 2016/04/13 - Problem fixed - Since today, the [wrong] segmentation of BUFR messages has been removed at CLS. They may now be extended up to 500 kbytes. Bulletins IOBX06 KARS were mostly concerned. In parallel, the first digit of Antarctic buoy WMO Ids has been forced to '7'. In the never-validated WMO template, this BUFR element (WMO region area - 0 01 003) could not be '7'. So, it was '0'. In BUFR template TM315009, the WMO Id is reported through a single 7-digit element.(0 01 087).
- 2016/04/08 - Problem - Bulletins generated by CLS America under header IOBX06 KARS contain two messages: one for platforms wrongly declared as being in subcategory 0 (ships), the other one for platforms declared as being in category 25 (data buoys). According to WMO code manual, a BUFR bulletin should have a single message.
- 2016/04/06 - Announcement - Meteo-France and CLS agree to postpone the end of the distribution of FM18 BUOY data to the 1st of September. This concerns those sent under headers with CCCC equal to LFPW, LFVW or KARS.
- 2016/04/01 - Problem - In ship BUFR messages, Metoffice increments the so called "update sequence number" for delayed data (those of which the header is fitted with RRA, RRB... This is not correct. Concerned bulletins are ISSA[A-L][01/11/16] EGRR.
...
MARCH 2016 .
- 2016/03/23 - Problem - Several BUFR messages sent by CLS America under header IOBX06 KARS (among others) for drifting buoys, are segmented. However, due to a wrong use of extension '(BBB)', a part of the data are not distributed: Meteo-France does not receive them. It seems the segmentation of GTS bulletins was necessary for TAC data that could not overpass 15 kbytes. This is no more an issue with binary data which bulletins may weight 500 kbytes.
- 2016/03/18 - Announcement - All drifting buoy data are now transmitted onto the GTS in BUFR. Template TM315009 is used by almost all producing centres. SIO (IOBX01 KWBC) and JMA (IOB[A-L]01 RJTD) are still using the never validated template for about 80 and 2 buoys respectively. SIO plans to apply template TM315009 by mid-April, JMA during the second half of 2016.
- 2016/03/11 - Problem fixed - All drifting buoys processed by CLS America now send their data in BUFR (TM315009 - IOBX06 KARS).
- 2016/03/09 - Problem fixed - The dataflow from Pacific Gyre (IOBX06 KARSKWBC), interrupted on the 28th of February, re-started.
- 2016/03/08 - Problem fixed - Joubeh reports correct BUFR data now (CCCC = CWAOIOBX12 and IOBX15 CWAO).
- 2016/03/07 - Problem -Joubeh Joubeh does not report correct BUFR messages yet (CCCC = CWAO).
- 2016/03/04 - Problem - It It seems that many observations are missing in BUFR messages produced by CLS America (TM315009 - IOBX02 IOBX06 KARS). A significant number of buoys processed by this centre have their data sent in FM18 BUOY format only.
