Systematic anomalies in the recent global atmospheric CO2 concentration
Fig 5
Comparison of anomaly (shaded) in amount versus growth rate.
a. Time series of annual residuals from hemispheric MLO and CGO baselines for different combinations of MLO and CGO or SPO data with the 2009–2015 CO2 anomaly, shown by shading. b. Corresponding annual growth rates, calculated from the same data, with the anomaly not clearly discernible. Growth rates are plotted halfway between the two years defining them as their difference.
