Atmospheric CO2 Concentration

The image shows the component of the atmospheric CO2 concentration that results from the net ecosystem exchange (NEE), which is shown on the land surface. This "green CO2" is the flux due to the respiration of vegetation, respiration of soil microbes, and fire minus that taken up by ecosystem production.
