Webcaused by a divergence of flux away from the chamber toward the ambient atmosphere outside of the collar; this divergent flux is larger (causing a tendency for a greater underestimate of actual flux by the chamber measurement) for smaller collars [Healy et al., 1996]. These errors are reduced if the rim of the collar is inserted into the soil. WebSoil flux can be measured using an open-bottom soil chamber which is placed on the ground. The soil chamber is integrated with a Gasmet analyzer, forming a closed-loop system. The gas sample is circulated through the analyzer back to the chamber, and the concentration changes per chambers footprint area are measured over time.
