Terrestrial biosphere, is a measure of imperfect data and understanding of Total emissions and the estimated changes in the atmosphere, ocean, and The resulting carbonīudget imbalance ( B IM), the difference between the estimated Global process models constrained by observations. The ocean CO 2 sink ( S OCEAN)Īnd terrestrial CO 2 sink ( S LAND) are estimated with Atmospheric CO 2 concentration is measuredĭirectly and its growth rate ( G ATM) is computed from the annualĬhanges in concentration. Mainly deforestation, are based on land use and land-use change data andīookkeeping models. Production data, while emissions from land use and land-use change ( E LUC), Fossil CO 2Įmissions ( E FF) are based on energy statistics and cement The global carbon budget and their uncertainties. Here weĭescribe data sets and methodology to quantify the five major components of Important to better understand the global carbon cycle, support theĭevelopment of climate policies, and project future climate change.
