The dissemination of OSI SAF HY-2D 25 km and 50 km wind products with pre-operational status (OSI-116-a, OSI-116-b) on EUMETCast will start on 9 November. The HY-2D satellite was launched by the Chinese National Satellite Ocean Application Service (NSOAS) and carries an HSCAT scatterometer. NSOAS kindly provides the near-real time input data for the OSI SAF wind products. The data will be made available on EUMETCast in BUFR format.

Example file names:
