Global 3‐D Simulations of the Triple Oxygen Isotope Signature Δ(17)O in Atmospheric CO(2)
The triple oxygen isotope signature Δ(17)O in atmospheric CO(2), also known as its “(17)O excess,” has been proposed as a tracer for gross primary production (the gross uptake of CO(2) by vegetation through photosynthesis). We present the first global 3‐D model simulations for Δ(17)O in atmospheric...

The triple oxygen isotope signature Δ(17)O in atmospheric CO(2), also known as its “(17)O excess,” has been proposed as a tracer for gross primary production (the gross uptake of CO(2) by vegetation through photosynthesis). We present the first global 3‐D model simulations for Δ(17)O in atmospheric CO(2) together with a detailed model description and sensitivity analyses. In our 3‐D model framework we include the stratospheric source of Δ(17)O in CO(2) and the surface sinks from vegetation, soils, ocean, biomass burning, and fossil fuel combustion. The effect of oxidation of atmospheric CO on Δ(17)O in CO(2) is also included in our model. We estimate that the global mean Δ(17)O (defined as [Formula: see text] with λ (RL) = 0.5229) of CO(2) in the lowest 500 m of the atmosphere is 39.6 per meg, which is ∼20 per meg lower than estimates from existing box models.
