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.

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 does a stevenson screen face north?
A Stevenson screen faces north to ensure that the temperature readings it provides are not influenced by direct sunlight. By having the door of the screen facing north, it minimizes the impact of solar radiation on the thermometers inside, allowing for more accurate and consistent measurements of air temperature and humidity. This orientation helps standardize meteorological observations across different locations.

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
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 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 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."
