New insights into plant uptake of carbonyl sulfide aid global carbon cycle model
In a study published in Science on 14 November, NOAA and CIRES scientists and colleagues show that carbonyl sulfide (COS), a trace gas consumed by plants, provides quantitative evidence that gradients of COS during the growing season are controlled by plant uptake during photosynthesis. This in turn provides an independent measure of plant photosynthesis rates crucial for carbon cycle modeling, a ...
