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

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 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 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.
