Soil heat flux sensor (circle) (also known as "soil heat flux plate", "heat flow meter") is mainly used to measure the energy balance of the soil and the thermal conductivity of the soil layer. The soil heat flux sensor measures temperature gradients using a thermopile consisting of two different metallic materials. Thermopile detectors receive thermal radiation, which can generate a thermoelectric potential between two junctions of dissimilar materials. The output of the heat flux sensor is in the form of voltage, which is proportional to the heat flux, and its output voltage is a millivolt signal, which is read by the data acquisition system. The output radiation of the heat flux sensor is W/m2, usually expressed in G: G=mv sensitivity coefficient. Each soil heat flux sensor is given a calibrated sensitivity coefficient. In the process of use, we must pay attention to the front and back of the heat flux sensor. The correct placement is to face up, because after the soil surface absorbs the net solar radiation, the energy is transferred to the deep layer of the soil through molecular conduction, so that the lower layer of the soil Warming, that is to say, heat is transported downward from the ground, and the soil heat flux at this time is positive; conversely, when the soil surface temperature is lower than the deep layer temperature, heat will be output from the deep layer of the soil, and the soil heat flux at this time is Flux is negative. This process is called the heat exchange process in the soil. During the year, the soil heat flux changes with the seasons. In summer, the soil heat flux is positive, that is, heat enters the soil layer, and the value is large; in winter, the heat flux is negative, and the soil The heat in the atmosphere is released to the atmosphere, but to a lesser extent
