The open path eddy covariance systems measure sonic sensible heat flux, momentum flux, and the flux of other scalars between the atmosphere and earth’s surface. The system consists of a datalogger, fast response three-dimensional sonic anemometer, and fast response scalar sensors. An independent measure of temperature and humidity from a slow response sensor is also measured to calculate background meteorological variables. Horizontal wind speed and direction are computed by the datalogger from the three-dimensional measurements of wind made by the sonic anemometer.
