UK. Currently (late 2013) the UK BUFR radiosonde data on the GTS is reformatted TEMP reports (separate parts), within the Met Office high-resolution (two-second) BUFR reports are available. The high-resolution reports have undergone extensive testing and teething problems have been resolved, they will be transmitted on the GTS at some point. They use a new BUFR template that includes height but not pressure (in preparation for future radiosondes that may not include a pressure sensor). An article on the O-B statistics for TEMP, BUFR and BUFR with treatment of radiosonde drift has been submitted to ASL (treatment of drift gives some improvement to the upper-level statistics, for consistent improvement the correct time has to be used as well as the correct horizontal location). Operational assimilation of the high-resolution UK reports (including treatment of drift) in the UKV system is expected to start in about April 2014. Global assimilation of some BUFR data (radiosonde and surface) is expected to start later in 2014 following a period of monitoring.
