PREFERRED TERM

closed-path eddy-covariance system  

DEFINITION

  • Measures the flux of atmospheric trace constituents by combining high speed (e.g. 100 Hz) observations of the trace constituent (CO2, H2O) and the 3D wind field by means of a sonic anemometer. The sonic anemometer measures the wind field in all the directions by sending sound pulses from an emitter to a detector, where the time lag depends on distance travelled (known), sound speed (known from air density), and wind speed.
