The Stevenson screen is a type of instrument shelter that is used to house meteorological instruments, such as thermometers and barometers. It is designed to protect the instruments from the elements while still allowing for accurate measurements.
The Stevenson screen is typically made of wood, with louvered sides to allow for air circulation. It has a double roof, with the inner roof being insulated. The screen is painted white to reflect sunlight and is mounted on a stand that raises it off the ground.
The Stevenson screen has several important characteristics that make it suitable for housing meteorological instruments:
* It is well-ventilated. The louvered sides of the screen allow for air circulation, which helps to prevent the instruments from overheating.
* It is insulated. The insulated roof of the screen helps to protect the instruments from extreme temperatures.
* It is white. The white paint of the screen reflects sunlight, which helps to keep the instruments cool.
* It is raised off the ground. This helps to prevent the instruments from being affected by ground heat.
The Stevenson screen is a valuable tool for meteorologists and other scientists who need to collect accurate weather data. It is a well-designed instrument that provides a protected environment for meteorological instruments.
Here are some additional characteristics of the Stevenson screen:
* The dimensions of the Stevenson screen are 1.8 meters wide, 1.2 meters deep, and 2 meters high.
* The screen is made of wood, with a double roof and louvered sides.
* The roof is insulated with a layer of felt or foam.
* The screen is painted white to reflect sunlight.
* The screen is mounted on a stand that raises it off the ground.
* The Stevenson screen is a standard instrument that is used by meteorological stations around the world.
