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 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 have the operational status now. AWDP version is 3_2_03.
The EARS ASCAT winds have been unavailable between 31 August 12:00 and 2 September 12:00 UTC due to a ground segment anomaly.
The Metop-C EARS ASCAT are now available on EUMETCast.
First development version of ASCAT-C regional 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. In the context of this regional service, data are acquired locally by a network of AHRPT stations, located within the North Atlantic, Europe and Indian Ocean regions and processed jointly by the EARS ground system and KNMI. From the sensing time of the last measurement in a product, it takes approximately 15 minutes to get the corresponding wind product ready at KNMI. The timeliness is in line with the goals of the EARS service for products generated from satellite direct broadcast data.
This product in intended for nowcasting applications, where high timeliness and resolution are very important.
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.
