Other stations of the global CO2 measurement network show almost exactly the same; the most important regional variation is the greatly subdued seasonal cycle at stations in the southern hemisphere.

The CO2 is sampled from air that is above the Boundary Layer; ostensibly free from surface effects.The Keeling Curve has the longest history of CO2 continuous measurements; but over the past 50 years a network of similar stations has become active.
In conclusion, the present atmospheric measurement network, current information on air - sea fluxes and current understanding of vertical atmospheric transport are not sufficient to allow full use of the potential of inverse modelling techniques to infer geographically detailed source - sink distributions of anthropogenic CO2.
We did so by estimating monthly fluxes and their uncertainty over a one - year period between June 2009 and May 2010 from 1) observational data collected in existing networks of surface CO2 measurement sites (GLOBALVIEWCO2 2010; extrapolated to the year 2010) and 2) both the surface observations and column - averaged dry air mole fractions of CO2 (XCO2) retrieved from GOSAT soundings.
