How has the CGMS cooperation benefitted your agency to date? […]

About CGMS

The Coordination Group for Meteorological Satellites (CGMS) is the group that globally coordinates meteorological satellite systems. This includes 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 […]

Governance

Charter The objectives of CGMS are formalised within its Charter: CGMS provides a forum for the exchange of technical information on geostationary and polar-orbiting meteorological satellite systems and research & development missions, such as reporting on current meteorological satellite status and future plans, telecommunications matters, operations, intercalibration of sensors, processing algorithms, products and their validation, […]

History, achievements

History The Coordination Group for Geostationary Satellites came into being on 19 September 1972, when representatives of the European Space Research Organisation (since 1975 called the European Space Agency, ESA), Japan, the United States of America, Observers from the World Meteorological Organisation (WMO) and the Joint Planning Staff for the Global Atmosphere Research Programme met […]

Objectives

Objectives The main goals of the coordination activities of the Coordination Group for Meteorological Satellites are to support operational weather monitoring and forecasting as well as climate monitoring, in response to requirements formulated by WMO, its programmes and other programmes jointly supported by WMO and other international agencies. It is the policy of CGMS to […]

Space weather coordination group

​Space Weather Coordination Group (SWCG) The CGMS Space Weather Coordination Group (SWCG) was established by the 46th CGMS plenary on 8 June 2018, building upon the work performed by the former Space Weather Task Team, created in 2015 during CGMS-43. SWCG co-chairs: Elsayed Taalat, NOAA / Tsutomu Nagatsuma NICT/JMA SWCG rapporteur: Andrew Monham, EUMETSAT SWCG […]

International Cloud Working Group

International Cloud Working Group: ICWG The International Cloud Working Group (ICWG) was established as a formal Coordination Group for Meteorological Satellites (CGMS) working group in 2014. The working group organises biennial workshops (about every 24 months), with its first workshop in 2016. It provides a forum for operational and research users of cloud parameter retrievals […]

International Precipitation Working Group

International Precipitation Working Group: IPWG The International Precipitation Working Group (IPWG) was established as a permanent Working Group of the Coordination Group for Meteorological Satellites (CGMS) on 20-22 June 2001 in Ft. Collins, CO, USA. The IPWG is co-sponsored by CGMS and the World Meteorological Organization (WMO) and focuses the scientific community on operational and […]

International Radio Occultation Working Group

The IROWG is co-sponsored by CGMS and the World Meteorological Organization (WMO). IROWG serves as a forum for operational and research […]

International TOVS Working Group

International TOVS Working Group: ITWG The International TOVS Working Group (ITWG) is convened as a sub-group of the Radiation Commission of the International Association of Meteorology and Atmospheric Sciences (IAMAS) and of the Coordination Group for Meteorological Satellites (CGMS). ITWG continues to organise International TOVS Study Conferences (ITSCs) which have met every 18-24 months since […]

International Winds Working Group

International Winds Working Group: IWWG The International Winds Working Group (IWWG) held its first meeting in 1991 and became a formal working group of the Coordination Group for Meteorological Satellites (CGMS) in 1994. The group addresses the science and applications of winds derived from feature tracking in consecutive satellite measurements (images), ocean surface winds and […]

Organisation

Organisation EUMETSAT is the permanent secretariat of the CGMS and responsible for securing the annual plenary session, following up of plenary actions, guiding CGMS during the inter-sessional periods between plenary sessions, guiding the CGMS working groups, and general management and administration. Working groups There are five CGMS Working Groups: WG I on satellite systems and […]

Working Group I

Working group I (WG I): Satellite systems and operations The CGMS Working Group I on Telecommunications was originally set off, together with the Working Group on Meteorological products, as part of the decisions taken in the CGMS-18 plenary meeting in Geneva (CH) in 1989. The rational of the decision was based on the need to […]

Working Group II

Working group II (WG II): Satellite data and products Working Group II, on satellite data and products, meets at the annual CGMS plenary sessions usually before the plenary session. The WG II meeting has a membership consisting of specialists on the delegations of participating CGMS members. Although participation is left to the discretion of the […]

Working Group III

Working group III (WG III): Operational Continuity and Contingency Planning The Working Group on Contingency Planning (WG III) was established in 1992 in order to deal with the risk of discontinuity in the key data services provided to WMO, and with contingency action planning to mitigate such risks. The approach to contingency planning involves global […]

Working Group IV

Working Group IV (WG IV): Data access and end user support Background CGMS Working Group IV was first initiated in 1989 to focus on global issues on satellite systems and telecommunication coordination. In 2001, it evolved to adress global data dissemination and it further evolved and changed its focus in 2018 and now addresses data […]

Satellite Status

Latest satellite status and plans Satellites operated by CGMS Members are listed in a set of tables that are maintained by the WMO Space Programme office on behalf of CGMS. The tables indicate the current status of on-orbit satellites along with the plans for future ones including launch date, orbital characteristics, payload and operational status […]
