Abstract:
There are two soil surface temperature measurement methods at present: One is the foursensorcombination mode and the other is the single sensor mode. Through the analysis on the measurement mode of soil surface temperature sensor and the signal acquisition principle, the authors discuss a measuring technique of using the single temperature sensor to substitute four temperature sensors. Besides, the improvement of measurement mode meets requirement of the groundbased weather observation standard of 2003 edition issued by the China Meteorological Administration. It has guaranteed uniformity and commensurability of the measurement mode of soil surface temperature. Meanwhile it cuts down the breakdown probability of temperature sensor and reduces the maintenance cost of AWS, which is easy to promote the application.
