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 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.
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.

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 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.
Why does the stevenson screen have a double top?
