Because soil CO2 flux is a significant component of the carbon cycle, it is an important variable in studies of global climate change.
Closed systems, such as the LI-8100A, deploy a chamber on the soil surface for a short period of time. The system circulates air from a chamber to a gas analyzer, and then back to the chamber. Flux is calculated from the rate that the CO2 concentration increases inside the chamber.
