Gross primary productivity: Quantifying the unmeasurable using flux measurements of carbonyl sulfide
At the ecosystem-scale, gross primary productivity (GPP) cannot be measured directly, but instead proxy measurements have to be used together with some sort of modeling approach. In this seminar I will present the eco-physiological rationale for using flux measurements of carbonyl sulfide (COS or OCS), the most abundant sulfur-containing atmospheric gas, as a proxy for GPP, demonstrate its application using case studies in several different biomes, as well as discuss shortcomings of the approach and future research directions.
