Greenhouse gas static chamber construction
WebThe NIST GHG Measurements Program develops technologies to measure emissions directly based on atmospheric observations from towers, aircraft and satellites. By combining economic data with atmospheric observations, scientists can provide stakeholders with emissions estimates that are more accurate, and have lower … Webgreenhouse gas fluxes include eddy co-variance measurements, which provide an integrated pic-ture of whole-ecosystem gas exchange, or static flux chambers, which facilitate identification of within-ecosystem variability. Both measurement techniques have inherent strengths and weakness; static chamber measurements better represent
