The Global Climate Observing System strives to meet the needs for climate-related observations for adaptation and scientific assessment. Long-term Global Climate Observing System records have enabled the Intergovernmental Panel on Climate Change (IPCC) to deliver the message that warming of the global climate system is unequivocal.
The Programme covers the total climate system through observation of the physical, chemical and biological properties of the atmosphere, oceans and land surface. It is built on the WMO Integrated Global Observing System (WIGOS), the Global Ocean Observing System (GOOS) and other research and operational observing systems. It includes both in situ and remote-sensing components, with space-based components coordinated by the Committee on Earth Observation Satellites (CEOS) and the Coordination Group for Meteorological Satellites (CGMS).
