ASCAT Storm Page

The storm centered imagery presented on this page are generated based on storm center files provided by NRL(Naval Research Laboratory at Monterey). These files are updated whenever new information about active storms become available, and the imagery is updated shortly after reciept of these files.

The following map displays the ocean surface winds at a 10m height from today's satellite passes as processed by NOAA/NESDIS, from near real-time data collected by the Advanced Scatterometer (ASCAT) aboard the EUMETSAT METOP satellite. For additional information about the EUMETSAT METOP or ASCAT programs, please visit the EUMETSAT Polar System (EPS). In Europe, KNMI is responsible for the ASCAT wind products, and additional information can be found at the EUMETSAT Ocean and Sea Ice Satellite Application Facility (OSI SAF).

The current empirically derived model function being used by to relate normalized radar cross-section with wind speed and direction is referred to as ASCAT1. The map below has been divided into 30x20 degree bins for closer examination between latitudes 80N to 80S and longitudes 180W to 180E. Just click on the desired geographical location and hopefully a closer look will be provided. Any comments or suggestions are welcome.

Please Note: While these wind data are obtained from the operational data stream available at NOAA/NESDIS, this web site is not maintained with 24x7 support.

The KNMI wind vector quality flag is being used at this time.


The wind vector retrievals flagged as potentially being corrupted are replaced with black circles.

The NOAA ASCAT wind products are in their validation phase.
The ASCAT wind products displayed here should be considered pre-operational.
