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.

What is the use of a metal stand on stevenson screen?
A metal stand on a Stevenson screen serves to elevate the screen above the ground, ensuring that it is placed at an appropriate height for accurate temperature and humidity measurements. This elevation helps to minimize the influence of heat from the ground and surrounding surfaces, thereby providing more reliable data. Additionally, the metal stand enhances the stability and durability of the Stevenson screen, protecting it from environmental factors.
Can be a stevenson screen be placed on a hard surface?
Yes, a Stevenson screen can be placed on a hard surface, but it is important to ensure that the screen is elevated and well-ventilated to avoid heat from the ground affecting the temperature readings. Ideally, it should be situated on a grassy or natural surface to minimize heat absorption and provide more accurate measurements. Proper placement is crucial for maintaining the integrity of the data collected.
Why was the Stevenson screen named after Thomas Stevenson?

Why does stevenson screen have longer legs?
A Stevenson Screen has longer legs to elevate the enclosure above ground level, minimizing the influence of heat from the ground and surrounding surfaces. This design helps ensure that the temperature readings inside the screen are more representative of the ambient air temperature rather than being affected by heat radiating from the ground. Additionally, the height aids in protecting the instruments from direct sunlight and precipitation, contributing to more accurate and reliable measurements.
What instruments are stored in the stevenson screen?
thermometer

Why is the stevenson screen placed one meter high from the ground?
The Stevenson screen is placed one meter above the ground to ensure accurate temperature and humidity readings while minimizing the influence of ground heat and moisture. This height helps to avoid distortions caused by surface temperatures, vegetation, or heat from buildings. Additionally, it allows for consistent measurements in various weather conditions and maintains standardization in meteorological observations.
Why is a stevenson screen off the ground?
because it is
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 are the instruments placed which helps to measure air temperature?
it is placed in the Stevenson Screen to shelter it from direct sunlight
Why was the stevenson screen raise 121cm above the ground?
The Stevenson screen is raised 1.25 meters above the ground to ensure accurate temperature measurements. Placing the screen at this height helps minimize the effects of ground radiation, which can distort temperature readings. By elevating the screen, it allows for proper ventilation and prevents the collection of heat from the ground, providing more reliable temperature data for meteorological purposes.
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.
Where should a stevenson screen be placed?
Well, honey, a Stevenson screen should be placed in an open area, away from any obstructions that could mess with the temperature readings. Don't go sticking it next to a building or under a tree, that's just asking for trouble. And for heaven's sake, make sure it's not in direct sunlight, or you'll be getting some wonky data faster than you can say "hot mess."
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.

When was the Stevenson Screen invented?
In the 1860s. I think. By Thomas Stevenson.
