Upgrade of wind processing chain in preparation of introduction of Land Contamination Ratio in ASCAT input data. AWDP version is 3_3_01.
The ASCAT-C wind products have been unavailable on 14 Mar between 7:15 and 12:48 UTC sensing time due to an instrument anomaly.
The ASCAT-C 25 km global wind products are available on the GTS as of 30 November.
The ASCAT-C wind products have been unavailable or delayed between 17 February 8:00 and 18 February 7:00 UTC sensing time due to a ground segment anomaly.
The ASCAT-C wind products have been unavailable on 22 Jan between 15:30 and 21:00 UTC sensing time due to an instrument anomaly.
ASCAT-C winds are available on EUMETCast for all users. Only the wind parameter has operational status - the soil moisture parameter (from the H SAF) currently has demonstration status.
ASCAT-C winds have the operational status now. AWDP version is 3_2_03.
The wind products have been unavailable between 24 Apr 18:00 and 29 Apr 10:00 UTC sensing time due to a ground segment anomaly.
First development version of ASCAT-C global wind product. AWDP version is 3_2_02.
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-C 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.
Note: This web site is not supported on a 24x7 basis and it should not be considered operational.
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. The BUFR products are available on the Global Telecommunication System (GTS), as well. The messages are distributed to the Exeter node and can be identified by: header (T1T2A1A2ii) = ISXX[01-06]; CCCC = EHDB.
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.
