In order to make the measured temperature representative, a louver box is placed on the natural lawn, and the height of the thermometer placed in the louver box is 1.5m from the ground, which is the unified standard of the World Meteorological Organization. The data measured in this way represents the standard temperature in the natural state without any interference, that is, the temperature we see in the weather forecast.
The door of the louver opens to the north, because China is located in the northern hemisphere. Opening to the north can prevent the sun from shining directly on the instruments in the box during observation and recording, which will affect the observation results.
