All values in billion tonnes of carbon per year (GtC/yr), for the globe. For values in billion tonnes of carbon dioxide per year (GtCO2/yr) , multiply the numbers below by 3.664.                                   
Note: 1 billion tonnes C = 1 petagram of carbon (10^15 gC) = 1 gigatonne C = 3.664 billion tonnes of CO2                                        
All uncertainties represent ± 1 sigma error (68 % chance of being in the range provided)

The atmospheric CO2 growth rate (variable uncertainty around 0.2 GtC/yr from 1980) is estimated directly from atmospheric CO2 concentration measurements, and provided by the US National Oceanic and Atmospheric Administration Earth System Research Laboratory (NOAA/ESRL).  http://www.esrl.noaa.gov/gmd/ccgg/trends/global.html

  1959-1980 are based on Mauna Loa and South Pole stations as observed by the CO2 Program at Scripps Institution of Oceanography. http://scrippsco2.ucsd.edu/data/atmospheric_co2/                              
  1980 onwards are global averages estimated from multiple stations run by NOAA/ESRL.                                        
The ocean sink (uncertainty of ±0.5 GtC/yr) is estimated from the average of several global ocean biogeochemistry models that reproduce the observed mean ocean sink of the 1990s.

The land sink (uncertainty of ±0.9 GtC/yr on average) was estimated from the average of several dynamic global vegetation models that reproduce the observed mean total land sink of the 1990s.

The budget imbalance is the sum of emissions (fossil fuel and industry + land-use change) minus (atmospheric growth + ocean sink + land sink); it is a measure of our imperfect data and understanding of the contemporary carbon cycle.
