GEO Carbon Project


Working to promote interoperability and provide integration across the Group on Earth Observations (GEO).


The development of an integrated global carbon cycle observation system to monitor changes in the carbon cycle, and ultimately the climate system, across the globe is of crucial importance in the 21st century. This system should be comprised of space and ground-based observations, in concert with modelling and analysis, to produce more robust budgets of carbon and other greenhouse gases (GHGs). A global initiative, the GEO Carbon and GHG Initiative, is working within the framework of Group on Earth Observations (GEO) to promote interoperability and provide integration across different parts of the system, particularly at domain interfaces. Thus, optimizing the efforts of existing networks and initiatives to reduce uncertainties in budgets of carbon and other GHGs. This is a very ambitious undertaking; therefore, the initiative is separated into tasks to provide actionable objectives.

Task 3 focuses on the optimization of in-situ observational networks. The main objective of Task 3 is to develop and implement a procedure for enhancing and refining the observation system for identified essential climate variables (ECVs) related to the carbon cycle that meets user-defined specifications at minimum total cost. Current observing efforts and initiatives are a mix of regional and global efforts, requiring a global coordinating mechanism that provides useful and comparable information to resource managers and policy makers reach Sustainable Development Goals (SDGs).
