Utilising specialist expertise from the Member States, Satellite Application Facilities (SAFs) are dedicated centres of excellence for processing satellite data. They form an integral part of the distributed EUMETSAT Application Ground Segment.

The eight EUMETSAT SAFs provide users with operational data and software products, each one for a dedicated user community and application area.

EUMETSAT Secretariat supervises and coordinates the overall activities of the SAF network, ensuring that the SAFs in operations are providing reliable and timely operational services related to the meteorological and environmental issues.

The SAF Network manages and coordinates interfaces between the SAFs themselves and between SAFs and other EUMETSAT systems, overseeing the integration and operations of SAFs into the overall ground segment infrastructure. During this process EUMETSAT ensures that services are delivered in the most reliable and cost-effective way.     

SAF Network

The Product Navigator has a full list of EUMETSAT centrally produced and SAF products.

Satellite Application Facilities

The Satellite Application Facilities (SAFs) are a distributed network of thematic application facilities responsible for necessary research, development, and operational activities not carried out by the central facility. The SAFs are located within the National Meteorological Services (NMS) of EUMETSAT Member States, or other agreed entities linked to a user community.

SAFs deliverables can be a specific piece of software to be made available to users for use in their own environment, or data and products made available in near real-time or offline.

The map below shows the deployment of the SAF Operational Architecture. Distributed architecture are indicated by a red dot, by selecting it, the relevant operational subsystem details will be displayed.



Product Validation

Products generated within the Application Ground Segment are subject to a validation process to ensure the correct quality of product has been reached. All products need to meet validation criteria before an "operational" product status can be applied. Corresponding validation reports are made available at the time of the product release.

Archiving Data and Products

All data and products generated within the Application Ground Segment are archived and can be retrieved, on demand, by users. The EUMETSAT Data Centre provides the central archive facility and retrieval service. The network of SAF archives provides thematic archive and retrieval services for their products. Products from the SAFs can be ordered centrally via the Data Centre.

SAF Projects

What is a SAF?

SAFs are dedicated centres of excellence for processing satellite data, achieved by utilising specialist expertise from the Member States. SAFs generate and disseminate operational EUMETSAT products and services and are an integral part of the distributed EUMETSAT Application Ground Segment.

Each SAF is led by the National Meteorological Service (NMS) of a EUMETSAT Member State, in association with a consortium of EUMETSAT Member States and Cooperating States, government bodies and research institutes. The lead NMS is responsible for the management of each complete SAF project. The research, data and services provided by the SAFs complement the standard meteorological products delivered by EUMETSAT’s central facilities in Darmstadt, Germany.

EUMETSAT supervises and coordinates the overall activities of the SAF network and the integration of the SAFs into the various operations within the EUMETSAT Application Ground Segment. It manages and coordinates interfaces — between the SAFs themselves and between SAFs and other EUMETSAT systems — overseeing the integration of SAFs into the overall ground segment infrastructure. By overseeing the entire network of SAFs, EUMETSAT ensures that services are delivered in the most reliable and cost-effective way.

SAFs currently use data from meteorological satellites both in geostationary and polar orbit.

The SAFs help deliver a variety of benefits, including:

  • Improvements to short-range forecasting of severe weather hazards.
  • Support to the aviation, agriculture, construction, gas, water and electricity industries.
  • Better understanding of the causes and effects of pollution of the upper atmosphere and the depletion of ozone.
  • Early warning of hazards.
  • Better data for climate monitoring.
  • Improved information for land use, ecology, disaster monitoring and agricultural forecasting.
  • Benefits for sea transport, fishing and offshore industries.
  • Improved data for input to Numerical Weather Prediction and the availability of user software packages for operational applications.
  • Improved software packages and near-real time and offline products.

Visiting Scientist Programme

The main objective of the SAF Visiting Scientists (VS) programme is to allow experts/scientists from the EUMETSAT Member States, other than those involved in a particular SAF development, to acquire expertise in the field of the SAF activities/products. A second objective of the VS scheme is to allow scientists from other institutes to participate in, or contribute to, the SAF activities, in particular the algorithm development and product validation activities.

Types of Activities

Depending on whether the VS stay at their home institute or move to the visited institute, two main types of VS can be distinguished:

  1. Visiting Scientists (VS) who participate in the development activities of the SAF by spending a certain period of time at one of the SAF Consortium Institutes.
  2. Associated Scientists (AS) who participate in the development activities of the SAF but stay 'at home' (no change of location).

In certain cases it might be necessary to combine the two types of activities, i.e. the VS activity may be carried out partly at the visited institute and partly at home.

Opportunities for Visiting Scientists

Current visiting scientist opportunities can be found at the relevant SAF web pages or acquired through the SAF help desk.

Overall Planning

SAF Network Evolution towards the MTG and Post-EPS Era

SAF Network Evolution towards the MTG and Post-EPS Era

Following Initial Developments and Operations (1996–2006), the SAFs went into the Continuous Development and Operations Phase (CDOP), which is approved in five-yearly segments by the Council.

The chart (right) shows the SAF Network Evolution towards the MTG and Post-EPS Era.

SAF Life Cycle

The SAF Development Life Cycle is optimised in line with the specific project organisation and expertise available from the participating partners.

Necessary scientific prototyping and development are performed in the SAF projects, with concurrent engineering of the required infrastructure and enabling software elements.

The Operations Life Cycle includes the delivery of the intended services or software applications to end-users, as well as the continuous Research and Development aiming at improving the targeted products, in line with user feedback.

A simplified view of the main activities performed during SAF development is illustrated in the following diagrams, in a phased approach going from Requirements Definition, to Design, Implementation, Integration, and Pre-operational activities.

Life Cycle Process Overview

SAF Life Cycle

Scientific analyses and prototyping are the basis for the definition of the SAF Products and underlining algorithms. The transfer from the Scientific Process to the Engineering Process is a continuous activity during the SAF Life Cycle. Engineering of SAF Products, according to user requirements, and to the expected quality standards, therefore, takes into account the need for a strong interaction between these two processes, up to the final validation of the deliverable products.

Evolutionary SAF Development Process

When a phased development approach is not appropriate, an evolutionary prototyping life cycle is adopted, to ensure an incremental release of the products to users, from the early stage of the development. Providing early feedback, Beta-users contribute to a controlled evolution of the products up to the last planned build.

Based on assessed user needs, the SAF User Requirements are established and implemented into a Technical Specification and Design baseline, in line with scientific assessments and plans.

SAF Requirements Engineering Process

The SAF design is refined down to the identified developmental components. Pre-developments and scientific prototyping take place to confirm the baseline and prepare for full engineering of the SAF products. Plans for verifications and validations, as well as for SAF configuration management, are also consolidated.

SAF Design Engineering Process

The identified SAF components are developed, or made available, as reused items. The SAF components are individually integrated and tested. Preparation for the SAF system level integration follows.

SAF Engineering Process

A Verification and Validation Results Review takes place at the end of this process.

SAF Preparation for Operation

Following the validation of the SAF products, the SAF infrastructure is prepared for supporting operations. An operation readiness review takes place prior to starting provision of services to users.

SAF Validation Process
