The EUMETSAT SAF Web pages
The SAF Network Web Pages were recently upgraded and improved, to provide more information on the SAF Network, SAF Projects, Targeted Products, and running SAF Demonstrators.
The SAF public documentation is available on the EUMETSAT Web.
The new SAF Web pages can be seen at the following address: http://www.eumetsat.de/saf/
