Metop ASCAT 6km Winds

Demonstrational : we welcome very much your feedback. Near real time product

The OSI SAF ASCAT winds from Metop-B are available on a high resolution swath grid size of 6km as a demonstration product, parallel to the existing operational 25km and 12.5km products. Several users have asked for a higher resolution product and we welcome very much your feedback if you are interested to evaluate the products. Based on the feedback we will consider whether or not a future operational status is useful for these products. The products are disseminated in BUFR and NetCDF format and they are available only on the KNMI FTP server, not through EUMETCast.

Comments

  • The winds are produced using the CMOD7 geophysical model function and contain stress-equivalent ECMWF background model winds as auxiliary data.
