Eddy Covariance

For landscape-scale (hectares to square kilometers) measurements of turbulent energy and gas exchange fluxes between ecosystems and the atmosphere, the micrometerological eddy covariance method is widely used. It relies on high frequency sensors and statistical analysis of the properties of turbulent-moving air parcels (eddies) to determine vertical fluxes.
This non-invasive method continuously averages the small-scale variability over a footprint area, dependent on measurement height and micrometeorological conditions, allowing for high temporal resolution.

At the moment we operate three systems:

• Eddy Covariance (H₂O/CO₂), Svalbard
• Eddy Covariance (H₂O/CO₂), Siberia
• Eddy Covariance (H₂O/CO₂/CH₄), Siberia

We plan to run a mobile Eddy Covariance (H₂O/CO₂) system in the field season 2008.
