Monthly global mean time evolution of CO2 concentrations (ppm) for the AIRS (red, from Jan 2003 to Feb 2017), the GOSAT (blue, from Jun 2009 to oct 2017), and the reconstructed data (cyan) from 2003 to 2017 (a); and scatter plot between the monthly global mean reconstructed data, and the AIRS (red) and the GOSAT (blue), respectively averaged during 2010–2016 (b). The reconstructed CO2 data from 2010–2013 and 2015–2017 compared here is from the historical and the SSP5-8.5 reconstructions, respectively.
