Short summary
Optical sampling expands our understanding of the "breathing" of terrestrial ecosystems beyond what is possible by eddy covariance alone. The light-use efficiency (LUE) model provides a useful conceptual framework for integrating optical and CO2 flux measurements. Contrasting optical and flux behavior can reveal distinct optical types that provide key information on flux controls. Practical applications include assessment of ecosystem health, productivity, and biospheric carbon sequestration.
