GCOS 1992-2012 - 20 Years in Service for Climate Observations
The year 2012 marks the 20th anniversary of the Global Climate Observing System (GCOS), the system dedicated to ensuring provision of the observational data and information that is the foundation for decisions on climate.
The GCOS Programme formally celebrated the 20th anniversary of the Global Climate Observing System on Friday, 29 June 2012 during the 64th WMO Executive Council meeting in Geneva. The celebration provided an opportunity to review the origins of the GCOS, to take stock of the accomplishments of GCOS in the first twenty years of its existence, and to think ahead about new opportunities and challenges for GCOS.
