The sonde anti-radiation device comprises a base, three base plates, three supports, three partition plates, an enclosing frame and three temperature sensors, wherein the three base plates are installed on the base, the three supports are installed on the three base plates respectively, the three partition plates are installed in the three gaps among the three base plates respectively, the enclosing frame is an annular plate, fixed outside the three partition plates and lower than the partition plates, the enclosing frame is separated to be three sections by the partition plates, the three temperature sensors are installed at the middle positions of the three enclosing frame respectively, and data lines of the temperature sensors are fixed on the enclosing frame and the supports. According to the sonde anti-radiation device and the method for obtaining the medium altitude temperature by the sonde, the problems that the temperature measurement error is big, accuracy degree is low, the structure is complex, and the construction cost is high due to solar radiation are effectively eliminated.

Description

technical field [0001] The invention belongs to the field of radiosonde technology, and in particular relates to a radiosonde anti-radiation device and a method for obtaining temperature by using the radiosonde. Background technique [0002] A radiosonde is a weather observing device attached to a balloon that typically measures atmospheric temperature, pressure and humidity, as well as wind, at various altitudes. [0003] The most important source of error in atmospheric temperature measurement is the solar radiation error of the temperature sensor. The radiosonde generally collects temperature in a hollow area 1-7 kilometers away from the ground, and the air in the hollow area is very thin and the solar radiation is large. The error of temperature measurement varies with increases as the radiosonde rises. At present, the heat transfer equilibrium state formula between the temperature sensor and the ambient atmosphere is used to reduce the temperature measurement error of ...

AI Technical Summary

Problems solved by technology

At present, the heat transfer equilibrium state formula between the temperature sensor and the ambient atmosphere is used to reduce the temperature measurement error of the radiosonde caused by convective heat transfer, but there is no device to slow down and eliminate the error caused by solar radiation
