Use stress-equivalent ECMWF model background winds rather than 10m real winds. PenWP version is 2_2_01.
ISRO has moved to data processing software version 1.1.3.
Some small bug fixes and improvements. PenWP version is 2_1_05.
First version for external distribution based on ISRO Level 1b version 1.1.2 data. PenWP version is 2_1_04.
At KNMI the backscatter products coming from the OSCAT scatterometer instrument on board the ScatSat-1 satellite are processed towards a 50 km product for the EUMETSAT OSI SAF. Details are described in the ScatSat-1 Wind Product User Manual.
The processing is done in near-real time. From the sensing time of the end of an input file, it takes approximately 2.5 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.
