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.

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.
to prevent heat radiation and damage by people or animals
In observataries,the thermometers are kept in a wooden box with good ventilation and air movement.This box is called stevenson's screen
because it is
