- Assimilation of BUFR SYNOP reports was started on 16 October 2013.
- Currently coordinates (latitude, longitude, and elevation) in BUFR is ignored and replaced by coordinates from Volume A, WMO Pub. 9.
- Current implementation picks BUFR if TAC for the same station is absent; the weight of BUFRs is little now but will grow when TAC reports are stopped
- Figure below is the number of stations reporting Any SYNOP (black), Only TAC (red), TAC and BUFR (purple), and Only BUFR (blue), observed at NWP system in JMA. The number of BUFR (purple + blue) firstly exceeds 50 % of entire SYNOP reports in mid-October 2014. But there are still 40+% of stations which does not (probably cannot) send BUFR.
