Radiosondes
CMC has been decoding Canadian upper-air data in BUFR since the beginning of 2014 on a regular basis. The gradual conversion to BUFR format of the Canadian upper air network is underway. The dissemination of BUFR data began in December 2013 and currently there are 15 radiosondes, out of 31, all Canadian sites are currently available on the GTS. For the time being, the full resolution profile (sampling every 2 secondssecond) is not yet available . Only a selection of vertical levels is sent on the GTSbut 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).
