Atmospheric measurements of the terrestrial O2 : CO2 exchange ratio of a midlatitude forest

Atmospheric Oxygen and Carbon Dioxide at Harvard Forest EMS Tower since 2006 M. Battle and W. Munger

Short summary
Predictions of global warming require predictions of how much CO2 will be taken up by the oceans, how much by land plants, and how much will stay in the atmosphere. Measurements of atmospheric oxygen (O2) help with these predictions if we also know the ratio of O2 release to CO2 uptake in land plants. We have measured this ratio in a midlatitude forest and find a lower value than the one in wide use. If truly applicable, our results call for a modest adjustment in the global carbon budget.
