Photosynthesis and Respiration at Leaf, Ecosystem, Regional, or Global Scales: Constraints, Measurements, and Modeling I
Session ID#: 8026
Session Description:
Photosynthesis and respiration are two coupled processes operating under fundamentally different mechanisms. While net biosphere-atmosphere CO2 exchange is routinely measured at the ecosystem scale, the gross photosynthetic and respiratory fluxes are only loosely constrained at ecosystem, regional, and global scales. Uncertainty in the responses of photosynthesis and respiration to the environment at these scales is a major source of uncertainty in predictions of biosphere-atmosphere feedbacks under climate change.
Advances have been made in developing methods to partition the measurable flux difference into photosynthetic and respiratory components. For example, eddy covariance CO2 flux partitioning, COS, SIF, isotopes, and PRI have all shown potential to derive process-specific information. We propose a session of measuring and modeling photosynthesis and respiration at any scale from the ecosystem to the globe to review recent advances in photosynthesis and respiration. We especially invite studies introducing novel methods that push the boundaries of carbon cycle science.
