Eddy Covariance: Measuring an Ecosystem's Breath

Date: 2017-04-18

Eddy Covariance is how an ecosystem’s “breathing” is measured, as explained in this video. It’s the CO2 and other gases that are exchanged between soil, vegetation, and the air in an ecosystem. The data it provides helps scientists to develop models that forecast long-term trends in CO2 and greenhouse gases.
