[0002] Surface temperature is one of the surface meteorological observation items. In the existing meteorological business, the main method used to measure the surface temperature is to place a platinum resistance temperature sensor on the underlying surface, which measures the surface temperature value of a single point on the underlying surface. , in the process of measuring the surface temperature, the platinum resistance temperature sensor needs to be in full contact with the underlying surface to be measured, half of the temperature-sensing part is in contact with the underlying surface, and the other part is in the air, so the measured temperature value is determined by the measured The average of the temperature of the underlying surface and the air temperature does not fully represent the measured surface temperature

Furthermore, in the actual measurement, it is necessary to make sufficient heat exchange between the temperature-sensing part of the platinum resistance temperature sensor and the measured ground surface to achieve thermal equilibrium to obtain the temperature value, so there is a delay in the measured temperature value. In addition, in today's In the observation of meteorological surface temperature, platinum resistance thermometers are limited by their own conditions. In the process of measuring surface temperature, they can only measure individual underlying surface types, such as bare land and grass, and cannot be used for water surfaces, ice surfaces, etc. The surface temperature is measured;

[0003] The infrared sensor calculates the temperature value of the measured object by measuring the infrared radiation value emitted by the object. During the measurement process, it does not need to be in direct contact with the ground surface, and does not affect the distribution of the original temperature field of the underlying surface to be measured. Its measurement range is wider. Wider range, higher accuracy, and stronger adaptability, the measured temperature is the surface temperature of the ground, and the measured value is more symbolic. Even if the underlying surface is made of different materials, it can be directly measured, but in the actual measurement environment Among them, its measurement accuracy is also easily affected by external factors, such as the emissivity of the measured surface, the distance between the sensor probe and the underlying surface, etc. Therefore, the present invention proposes an infrared surface temperature observation system and its observation method.
