Abstract

An eddy-correlation method is the basis of a newly-developed sensible heat-flux detector which collects air temperature information proportional to the vertical wind speed in two electronic counters, one for upflow and one for downflow. The current model uses fast-responding sensors for vertical velocity and air temperature, but the principle should be applicable to the measurement of other kinds of fluxes. Values of sensible heat transport above bare soil and above grass have been determined, from which a sampling duration of one hour has been found to be suitable. The system provides a relatively simple way to measure sensible heat fluxes and to determine the suitability of this flux technique for wider application.
