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

The Thermometer, hygrometer, psychrometer, dewcell, barometer and thermograph are all generally used in the Stevenson screen.

The sides of a Stevenson Screen are louvered to allow air to circulate through the Stevenson's Screen easily.
to prevent heat radiation and damage by people or animals
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.
In observataries,the thermometers are kept in a wooden box with good ventilation and air movement.This box is called stevenson's screen
