Description
Technical Field

Background
In the process of measuring the air temperature, the weather station temperature sensor is influenced by direct solar radiation, ground reflected radiation, long-wave radiation and scattered radiation, so that the measured value of the temperature measuring element is different from the real air temperature value. To reduce such radiation-induced measurement errors, effective radiation shielding measures must be taken with respect to the temperature sensing element. The radiation protection equipment commonly used in the current meteorological station comprises a louver box and a radiation protection cover. However, in the conventional louvres or radiation shields, the outer walls of the apparatus still have a certain absorption of radiation, and especially after the coating ages, the absorption increases rapidly, which causes the air flowing into the interior to be heated, which causes measurement errors. In addition, the structure of the louver box or the radiation-proof cover is not beneficial to the exchange of internal and external air flows, so that the change of the air temperature in the equipment lags behind the free air outside the equipment, and the response speed of the temperature measuring element is reduced.
A good meteorological temperature sensor design should both prevent as much radiation as possible from reaching the temperature sensing element surface, and increase the air flow velocity around the temperature sensing element as much as possible. At present, the first design requirement or the second requirement is easier to meet, but the two design requirements are difficult to meet at the same time.
