Coordination Group for Meteorological Satellites (CGMS)

The CGMS is an international forum for coordinating operational and R&D space agency activities in support of weather and climate monitoring, including forecasting, seeking to fulfil user requirements

The Coordination Group for Meteorological Satellites (CGMS) was formalised on 19 September 1972 by Japan, the USA, Europe and the WMO, in order to seek common ground on geostationary meteorological satellite programmes. Since then, the CGMS has come a long way, covering low-Earth and highly-elliptical orbit operational and R&D satellite programmes, including aspects to ensure that users can easily receive, retrieve and use the data and products for improved forecasting and other applications.

The CGMS’ objective is to globally coordinate operational and R&D meteorological satellite systems, including protection of in-orbit assets, contingency planning, improvement of quality of data, support to users, facilitation of shared data access and development of the use of satellite products in key application areas. The coordination is pursued from an end-to-end perspective, through development of multilateral coordination and cooperation across all meteorological satellite operators and with the user community, in particular the WMO and IOC-UNESCO, but also other entities.

Agencies from the CGMS and CEOS, together with the WMO, jointly developed the CEOS-CGMS Working Group on Climate, in charge of implementing the global architecture for climate monitoring from space.

The CGMS is also behind a number of initiatives, including the Global Space-based Inter-Calibration System (GSICS), the Sustained, Coordinated Processing of Environmental Satellite Data for Climate Monitoring (SCOPE-CM) and the Virtual Laboratory (VLab).

EUMETSAT joined the CGMS in 1987 and has been its permanent Secretariat since then. The CGMS is composed of members and observers. The CGMS Secretariat represents CGMS members in international bodies such as the Committee on Earth Observation Satellites (CEOS), the Group on Earth Observation (GEO), and the Space Frequency Coordination Group (SFCG).
