Atmospheric Composition Constellation (ACC)
In support of the Group on Earth Observations (GEO) objectives and as a space component of the Global Earth Observation System of Systems (GEOSS), CEOS has developed the concept of virtual, space-based Constellations. A Constellation is a coordinated set of space and/or ground segment capabilities from different partners that focuses on observing a particular parameter or set of parameters of the Earth system.
The CEOS Constellation for Atmospheric Composition (ACC) goal is to collect and deliver data to improve monitoring, assessment and predictive capabilities for changes in the ozone layer, air quality and climate forcing associated with changes in the environment through coordination of existing and future international space assets. The ACC Constellation directly addresses the Societal Benefit Areas of Disasters, Health, Energy, Climate, and Ecosystems.
