A new measurring technique of soil thermal inertia

摘要

Thermal inertia is the function of substance density, heatcapacity and heat diffusivity, and is an important parameter forresearching the process of surface heat balance using remote sensingtechnique. In this paper, using soil heat plates, infraredthermometer, data logger and other instruments, by man-controlledchanging the solar radiation status on the soil samples, the authorsgave a new method to measure soil thermal inertial.
