Use of argon to measure gas exchange in turbulent mountain streams [PDF]
Gas exchange is a parameter needed in stream metabolism and trace gas emissions models. One way to estimate gas exchange is via measuring the decline of added tracer gases such as sulfur hexafluoride (SF6).

Gas exchange measurements in the unsteady state
Leaf level gas exchange is a widely used technique that provides real‐time measurement of leaf physiological properties, including CO2 assimilation (A), stomatal conductance to water vapour (g sw ) and intercellular CO2 (C i ).
