A Stevenson screen is raised above the ground to ensure accurate and consistent measurements of meteorological data by preventing the influence of surface heat and moisture. This elevation helps to minimize the effects of nearby objects, such as buildings or vegetation, which can cause localized temperature variations. Additionally, being elevated allows for better airflow around the instruments, promoting more reliable readings of temperature and humidity. Overall, the height helps maintain the integrity of the data collected.

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.
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.
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 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.
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.
What are tramways?
passenger carrying systems that are raised on pylons above ground.
What is a large raised area that rises above that surrounding ground?
A plateau.
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.
Above Ground Pool Decks?
An above-ground pool can be a great choice for many homeowners and their families. When installing a raised deck for an above-ground pool, there are several important things to remember. It's essential to make sure that a raised deck can be connected to the lip of an above-ground pool. In some cases, an above-ground pool may be a separate structure from a deck. This can be a serious tripping hazard for people entering a pool.
