Where should the temperature be measured?

When measuring the temperature, choose a cool and ventilated place, a cool and ventilated place outdoors, that is, a spacious and unobstructed place that is not exposed to direct sunlight.

In meteorology, the physical quantity representing the degree of air heat and cold is called temperature, which is referred to as temperature for short. The international standard unit for temperature measurement is Celsius (℃).

The temperature mentioned in the weather forecast refers to the air temperature measured in the open air without direct sunlight (usually measured by blinds). The highest temperature is the highest temperature in a day, which generally appears in 14- 15. The lowest temperature is the lowest temperature in a day, usually before sunrise.

Specific introduction of shutter temperature measurement;

1, the data measured at 1 and 5 meters from the ground when the louver was placed on the lawn protected from direct sunlight, wind, rain and ventilation, and the thermometer was placed in the louver. This is the standard set by the World Meteorological Organization.

2. The four walls of the louver box are composed of two thin wooden boards, the outer louver inclines inward and the inner louver inclines outward, and the included angle between the louver and the horizontal plane is 45 degrees.

3. The function of the louver box is to prevent the direct radiation from the sun and the reflected radiation from the ground from shining on the instrument, and to protect the instrument from the influence of strong wind, rain and snow. And make the sensing part of the instrument properly ventilated, so as to truly sense the changes of the temperature and humidity of the outside air.
