HY-2B and HY-2C operational wind products from OSI SAF will be available on EUMETCast from 4 November 2021.

The products are:

  • HY-2B 25 km wind vectors (OSI-114-a)
  • HY-2B 50 km wind vectors (OSI-114-b)
  • HY-2C 25 km wind vectors (OSI-115-a)
  • HY-2C 50 km wind vectors (OSI-115-b)

The HY-2B and HY-2C satellites were launched by the Chinese National Satellite Ocean Application Service (NSOAS). NSOAS kindly provides the near-real time scatterometer data which are used as input for the generation of these OSI SAF wind products.
