Global Carbon Budget
Data

Data Sources

The annual update of the Global Carbon Budget is possible thanks to many institutions, observational networks and modeling groups around the world.

All datasets and modeling output to complete the Global Carbon Budget 2012 are described in detail in Le Quere et al. (2012) [http://bit.ly/UY8GTQ]

All datasets contributing to this year’s update have been integrated in one single file. It is archived at CDIAC doi: http://dx.doi.org/10.3334/CDIAC/GCP_V2012 (Excel, 263kb)
