| | 29-Sep-2011 |
No winds have been available between 28 September, 11:36 and 29 September, 2:21 UTC due to a Metop out of plane manoeuvre.

Description
The ASCAT Wind Product contains measurements of the wind direction and wind speed above the sea surface. The measurements are obtained through the processing of scatterometer data originating from the ASCAT instrument on EUMETSAT's MetOp satellite, as described in the ASCAT Wind Product User Manual.
The processing is done in near-real time. From the sensing time of the last measurement in a product, it takes approximately 2 hours to get the corresponding wind product ready at KNMI.
The last 22 hours of data are shown in two separate plots showing ascending and descending tracks, respectively. This is done to avoid overlap of data in the pictures. Note that also data from previous days can be displayed using the link on the right hand side. The overview plots show color coded wind speed measurements. If you click somewhere in the satellite track, a picture appears showing the scatterometer winds in more detail.
Product monitoring information in near-real time is available through the corresponding link on the right hand side.
Access to products
This wind product is available in BUFR and NetCDF format. The BUFR data are disseminated through the EUMETCast system; for access please contact EUMETSAT. The products are also available on a password protected FTP server (products of the last three days only). Contact the KNMI OSI SAF team for access.
For a swift response management procedure, user requests on this scatterometer wind data product should be issued at the Ocean and Sea Ice SAF website.
