The table here above shows the number of drifting buoys for which the observations were received by Meteo-France on the 6th of August. Figures are shared by the WMO code which was used: either FM18 BUOY, FM94 BUFR with template TM315009 or the never validated template for data buoys. This table also shows the number of observations which were received. One may see that more buoys now report in BUFR with template TM315009 than in FM18 BUOY code or BUFR with the old template.Only one buoy (CCCC=CWAO) is still reporting in "FM18 only". JMA remains the only NMS that did not migrate its BUFR production to the new template. Six buoys are only concerned. With these exceptions, one may say that 99.5% of the drifting buoys report in BUFR with template TM315009 (against 83% buoys that still report in FM18). With regards to the data volume, the difference is even higher: only 65% of drifting buoy observations are sent in FM18.
