Almost 70% of stations report in BUFR, about 20% report native BUFR with roughly 50% reporting reformatted TEMP (see "structure" page and plots below). Reports may be incomplete (eg data above 100 hPa missing). The UK has recently started is now sending high resolution BUFR from some stations in the standard template (it was using an alternate template before).On 11 November 2014 ECMWF started assimilating a subset of the high resolution reports and has gradually added more BUFR reports after careful checking. After 21 . In November 2014 some of the ASAPs (those starting ASDE and ASEU) also research vessel DBLK ASAP ships stopped reporting in TEMP SHIP format, they are now only available in BUFR format. We understand that a few NWP centres are not yet in a position to assimilate BUFR radiosonde data, although they are working on this. In early 2016 Spain stopped sending TEMP reports to some GTS nodes, but they are still received at ECMWF. In June 2016 a smattering of other stations (10141, 17516, 37789, 47155, 76743, 76903, 93817, green dots on the map) were BUFR only (one has BUFR problems and has been requested to resume sending TEMPs for now), one or two of these are new to the GTS and never reported in TEMP code.
(Grey: TAC reports but no BUFR, Purple: BUFR reports but no TAC, Red *: position error. Blue: both BUFR and TAC, light blue indicates fewer ascents in BUFR. Triangle - ship report, X - wind-only report.)
