Satellite Application Facilities (SAFs) are specialised development and processing centres within the EUMETSAT Applications Ground Segment.

SAFs will use inputs from meteorological satellites in both geostationary and polar orbits. Until data becomes available from systems such as Meteosat Second Generation (MSG) and the EUMETSAT Polar System (EPS), information from current satellites will be used for development.

Other relevant data will be obtained from the World Meteorological Organisation’s (WMO) Global Telecommunication System (GTS).

EUMETSAT SAF products will be distributed by satellite, via the GTS/RMDCN or by other means.

1.1 The SAFs within the EUMETSAT Application Ground Segment

EUM/SAF/VWG/02/0010, Rev. 3, May 2003 Page 5

The overall objective of a SAF is the provision of operational services, in the context of a cost-effective and synergetic balance between the central and distributed services.

The overall objective of a SAF is the provision of operational services, in the context of a cost-effective and synergetic balance between the central and distributed services.

The SAF services will be an integral part of the overall EUMETSAT operational services.

Establishing of a SAF is to undertake on a distributed basis such necessary research, development and operational activities that can be carried out in a more effective way than at the EUMETSAT central facility.

The primary role for the SAFs is to develop and deliver services and products aimed at enhancing the value and use of data for applications considered to be a common need of all, or the least a majority, of Member States.

1.2 The SAF Network

The SAF Network embraces the whole set of SAFs, as distributed elements of the EUMETSAT Application Ground Segment.

The Secretariat of EUMETSAT coordinates and monitors the development and operations of the entire SAF Network, based on the EUMETSAT standards and procedures.

The EUMETSAT STG (Scientific & Technical Group) and AFG (Administrative & Financial Group) review as appropriate the progress of the SAF development and operational phases.

2.1 Approved SAF Projects

EUM/SAF/VWG/02/0010, Rev. 3, May 2003 Page 10

2.1 Approved SAF ProjectsSeven SAFs Projects were approved, related Cooperation Agreements established, and development activities initiated in the period 1997-1999.

Two SAF Projects

- The SAF on Nowcasting & Very Short Range Forecasting- The SAF on Ocean & Sea Ice

already completed in the first part of 2002 their development phase and started the “so called” Initial Operations Phase, aiming at validating their MSG related products using the MSG-1 real data and completing their developments for EPS related products up to their validation using Metop-1 data.

The SAFs on NWP and Climate Monitoring will start their Initial Operations in early 2004, following approval of their Detailed Operations Proposals.

An 8th SAF Theme in Support to Operational Hydrology and Water Management has been approved by the Council in November 2002, thus creating a new SAF

opportunity.

The Development Extension (to 2006) for the O3M SAF was approved in June 2002.

The same approach is taken for the GRM SAF. The related proposal has been submitted and positively evaluated. Expected to be approved by Council in June 2003.

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 SAF Web pages can be seen at the following address: http://www.eumetsat.de/saf/

Further Improvements are planned in the short-term.
