涡流相关法是新开发的感热通量检测器的基础，该检测器在两个电子计数器上收集与垂直风速成正比的气温信息，一个是上升的，一个是下降的。目前的模型使用快速响应的传感器来测量垂直速度和空气温度，但该原理应适用于测量其他种类的通量。已测定了裸露土壤和草地上的感热输运值，从中发现取样时间为1小时是合适的。该系统提供了一种相对简单的方法来测量感热通量，并确定该通量技术是否适用于更广泛的应用。
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.
