English: The eddy covariance (also known as eddy correlation and eddy flux) technique is a key atmospheric flux measurement technique to measure and calculate vertical turbulent fluxes within atmospheric boundary layers. (From the English WP-page:Eddy covariance)

Measurement equipment

[edit]
  • English: Semi open path eddy covariance system, consisting of an ultrasonic anemometer to measure 3D air flow and infrared gas analyser (IRGA) to measure carbon dioxide. This system is situated at the top of a 20 metre high tower above a forest.
