CEOS, GCOS and GEO

EUMETSAT interacts with and supports international organisations such as CEOS, GCOS and GEO

The Committee on Earth Observation Satellites (CEOS) is an international coordinating mechanism involved in the management of international, civil, space-borne missions designed to observe and study the Earth.

The Global Climate Observing System (GCOS) was established in 1992 to ensure that the observations and information required to address climate-related issues are obtained and made available to all potential users.

The intergovernmental Group on Earth Observations (GEO) is leading a worldwide effort to build a Global Earth Observation System of Systems (GEOSS). 

CEOS

SIR CEOSThe Committee on Earth Observation Satellites (CEOS) is an international coordinating mechanism involved in the management of international, civil, space-borne missions designed to observe and study the Earth.

Comprised of Members (most of which are space agencies) and Associates (associated national and international organisations), CEOS is recognised as the major international forum for the coordination of Earth observation satellite programmes and for the interaction of these programmes with users of satellite data worldwide.

EUMETSAT has been a Member of CEOS since 1989 and is leading its activities mainly in the field of the CEOS constellation discussions on ocean surface topography, ocean surface wind, ocean colour, atmospheric monitoring and climate. EUMETSAT was instrumental in the creation of the CEOS-CGMS Working Group on Climate, in charge of implementing the global architecture for climate monitoring from space jointly developed by the WMO, CEOS and CGMS agencies. 

GCOS

SIR GCOS

The Global Climate Observing System (GCOS) was established in 1992 to ensure that the observations and information required to address climate-related issues are obtained and made available to all potential users.

The vision of GCOS is that all users have access to the climate observations, data records and information which they require to address pressing climate-related concerns. GCOS users include individuals, national and international organisations, institutions and agencies. The role of GCOS is to work with partners to ensure the sustained provision of reliable physical, chemical and biological observations and data records for the total climate system – across the atmospheric, oceanic and terrestrial domains, including hydrological and carbon cycles and the cryosphere.

The GCOS programme stimulates, encourages, coordinates and facilitates the taking of needed observations by national or international organisations to support their own requirements as well as common goals. It provides an operational framework for integrating and enhancing the observational systems of participating countries and organisations into a comprehensive system focused on the requirements of climate issues.

The GCOS programme does not directly make observations or generate data products. As a system of climate-relevant observing systems, it constitutes, in aggregate, the climate observing component of the WMO Global Observing System (GOS) and a contribution to the Global Earth Observation System of Systems (GEOSS). GCOS includes both in-situ and remote-sensing components, with its space-based components coordinated by the Committee on Earth Observation Satellites (CEOS) and the Coordination Group for Meteorological Satellites (CGMS).

EUMETSAT supports GCOS activities with the production of accurately calibrated and homogenised observations (fundamental climate data records) from its Metop, Meteosat and Jason satellites, contributing to more than half of the GCOS essential climate variables. 

GEO

SIR GEOS

The intergovernmental Group on Earth Observations (GEO) is leading a worldwide effort to build a Global Earth Observation System of Systems (GEOSS).

GEO was set up following calls for action by the G8 after the 2002 World Summit on Sustainable Development in Johannesburg, which highlighted a need for coordinated observations relating to the state of the planet to support decision making.

The group is a voluntary partnership of governments and international organisations – current membership includes 96 governments and the EC, as well as 87 intergovernmental, international and regional organisations which have “Participating Organisation” status (including EUMETSAT).

GEO provides a framework within which these entities can coordinate to develop new projects and work towards the key objective of the group: global access to affordable Earth observation data, which is being implemented through the creation of the Global Earth Observation System of Systems (GEOSS). The GEO Ministerial meeting of November 2015 endorsed a new GEO Strategic Plan for 2016-2025.

EUMETSAT is contributing to GEOSS through the development of the GEONETCast infrastructure with systems developed in cooperation with the CMA and NOAA, as well as INPE. A number of capacity-building or research projects are relying on the GEONETCast infrastructure to develop new operational services: e.g. the AMESD, MESA and PUMA projects, the DAWBEE project and a number of FP7 and H2020 projects.
