Why is the stevenson screen placed several feet from the ground?

It is kept 1.25m/4.1ft (UK standard) above the ground by legs to avoid strong temperature gradients at ground level, has louvred sides to encourage the free passage of air, and is painted white to reflect heat radiation, since what is measured is the temperature of the air in the shade, not of the sunshine.

Why was the Stevenson screen named after Thomas Stevenson?
he invented the instrument
What instruments are stored in the stevenson screen?
thermometer
Why does a Stevenson screen have double boarded sheet?
Bold Italic undrline
What is the function of air gaps in sides in Stevenson screen?
allows air to reach the thermometer so that it s temprature can be measured
Why stevenson screen has slatted sides?
to protect the instruments inside from the wind!

Why is a stevenson screen off the ground?

Where are the instruments placed which helps to measure air temperature?
it is placed in the Stevenson Screen to shelter it from direct sunlight
Where is the Stevenson screen found?
A Stevenson screen is typically found at weather stations to house temperature and humidity sensors. It is a white louvered box mounted on a stand about four feet off the ground to shield the sensors from direct sunlight and other weather elements, providing accurate readings.
Why was the stevenson screen raise 121cm above the ground?
To measure a more realistic temperature 🌡️
Why do you not put the stevenson screen on the ground?
The ground, like tarmac or concrete is a solid state which absorb sunlight due to the dark colour (e.g. black). Therefore there is probability that the Stevenson Screen can absorb these heat which can then alter the readings of the instruments. Hope that helps JL
Where should a stevenson screen be placed?
A Stevenson screen should be placed at least 1.25 meters above the ground in a sheltered area, away from direct sunlight, artificial heat sources, and reflective surfaces. It should be located in an open area to allow adequate ventilation for accurate temperature and humidity readings.
When was stevenson screen invented?
In the 1860s. I think. By Thomas Stevenson.

How do you take the temperature of air?
Assuming that you mean temperature (and not temputure - whatever that may be), it is measured using a thermometer which is placed at a height of 1.25 to 2 metres above ground level in a well-ventilated, white box called a Stevenson screen. A Stevenson screen will usually also contain other meteorological instruments to measure humidity, dew point and air pressure.Details for the setup are defined by the World Meteorological Organization (WMO).Incidentally, the box is named after a British Civil Engineer, Thomas Stevenson, who was father of the author, Robert Louis Stevenson.
Why are the sides of the 'stevenson screen' louvered?
The sides of a Stevenson screen are louvered to allow air to circulate freely around the temperature and humidity sensors inside. This design helps prevent the sun's direct rays from hitting the sensors and affecting the accuracy of the readings. The louvered sides also help to reduce the impact of thermal radiation on the inside of the screen.
