SYNOP
The CMC have has been decoding Canadian SYNOP in BUFR since the beginning of 2014 on a regular basis. Unfortunately, these data are not yet availble On 27 January 2015, the Canadian surface network started disseminating 72 synop stations (out of 875) in BUFR on the GTS. We are receiving these data internally.This was announced in the following GENOT in 2015:
As of 20 august 2015, SYNOP bulletins in BUFR are being disseminated by bundling all Canadian SYNOP reports. For more information, please consult the following GENOTs for main/intermediate SYNOP bulletins.

Canadian synop in BUFR will be examined in 2022-2023 for consideration in our NWP systems.
Radiosondes
The CMC have has been decoding Canadian upper-air data in BUFR since the beginning of 2014 on a regular basis. The upper-gradual conversion to BUFR format of the Canadian upper air network is now producing 9 radiosondes in BUFR but these data are still not made availble to the international community. It is distributed internally and not on the GTS.
underway. The dissemination of BUFR data began in December 2013 and all Canadian sites are currently available on the GTS. For the time being, the full resolution profile (sampling every second) is not yet available but will be shortly as the Upper Air Network will be transitioning to a new vendor. The pre-selection vertical levels will be replaced by high reolusion profiles in BUFR. Canadian BUFR data contain the drift of the radiosonde. For more information, please consult the following GENOT.
As of 28 October 2020 at 12 UTC, all Canadian upper air stations have transitioned to GRAW type radiosondes, except for Whitehorse (an old autolauncher).
