Is the weather forecast indoors or outdoors?

The temperature mentioned in the weather forecast refers to the air temperature measured outdoors without direct sunlight. The highest temperature is the highest temperature in a day, which generally appears at 14- 15, and the lowest temperature generally appears at 5-6 am. Of course, the maximum and minimum temperatures in different places will also change due to different weather conditions.

In artificial meteorological observation, in order to avoid the direct radiation of the sun, thermometers and sensors for measuring temperature are placed in louver boxes. The door of the shutter box opens to the north to prevent the sunlight from directly illuminating the instruments in the box during observation. Painting the shutter box white can basically reflect the sunlight projected on the shutter box. And white does not absorb heat easily.
