Trends in Atmospheric CO₂ - Globally averaged marine surface annual mean growth rates

Information Comments (0)

This dataset shows global atmospheric CO₂ trends (marine surface, annual average growth rates).

As mentioned by the source, “Annual CO2 mole fraction increase (ppm) from Jan 1 through Dec 31. The uncertainty in the global annual mean growth rate is estimated using a monte carlo technique that computes 200 time series of global annual growt rates, each time using measurement records from a different sampling of sites from the NOAA GML  cooperative air sampling network.  Each year has a different uncertainty. The last one or two years listed could have preliminary uncertainties set equal to the average uncertainty since 1980. Before 1980 the global growth rate has been approximated by taking the average of Mauna Loa and the South Pole, correcting for the offset between (MLO+SPO)/2 and the global Marine Boundary Layer, as described in Ballantyne et al, 2012”.
