Extracting insight on forest carbon cycles through observations and modeling

I will describe some of the observational approaches we have deployed to measure the net rate of carbon dioxide exchange between a forest ecosystem and the atmosphere. The observed net exchange of CO₂ represents the sum of several components of gross CO₂ exchange, which in turn represent fundamental tree and soil metabolic processes. One challenge we have had is: how do we extract insight about how these component processes might be responding to environmental change at various scales from an observed time series?
