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.

What is the function of long legs 1.25m above surface in Stevenson screen?
Long legs 1.25m above the surface of a Stevenson screen are meant to elevate the screen to ensure proper air circulation around the temperature and humidity sensors inside. This helps to prevent any interference from the heat radiating off the ground, providing more accurate measurements of temperature and humidity.
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
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.
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.
What is the purpose of a Stevenson screen?
A Stevenson screen is a standardized shelter used to protect meteorological instruments from direct sunlight and precipitation while allowing air to circulate freely around them. Its design typically features louvered sides and is elevated above the ground to ensure accurate temperature and humidity readings. The primary purpose is to provide a controlled environment for instruments such as thermometers and hygrometers, ensuring reliable weather data collection.
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."
What are the main characteristics of a steveson screen?
A Stevenson screen is a white slatted wooden box with a double roof design, used to shield temperature and humidity sensors from direct sunlight and precipitation. Its key characteristics include proper ventilation to ensure accurate measurements, a standard size of about 30 cm in height, and a location placed 1.25 to 2 meters above the ground.
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.

What are the features of the stevenson screen?
Instruments which are used to measure temperature and Humidity should be kept inside "stevenson screen". Its a wooden box to shade from direct sunlight, Its painted white to reflect sunlight, It has vents to allow free flow of air. The stevenson screen should be located away from trees and buildings which could affect the temperature!
