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

Weather instruments such as thermometers, hygrometers, and barometers are typically stored in a Stevenson screen. These instruments are used to measure temperature, humidity, and barometric pressure for meteorological observations.
Stevenson screens typically house instruments used in meteorology, such as thermometers, hygrometers, barometers, and sometimes rain gauges. These instruments are used to measure temperature, humidity, air pressure, and sometimes precipitation. The Stevenson screen provides shelter for these instruments to ensure accurate measurements.
Instruments which are used to measure temperature and Humidity should be kept inside "stevenson screen". Its a wooden box to shade from direct sunlight, Its painted white to reflect sunlight, It has vents to allow free flow of air. The stevenson screen should be located away from trees and buildings which could affect the temperature!
•Steven sun screen also known as meteorological screen and it is made by wood. •This screen is used at met. Center and it save the instruments from sun light and rain allowing the passage of air.

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.

In the 1860s. I think. By Thomas Stevenson.

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
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.
