The Stevenson Screen

A Stevenson Screen is a protective enclosure used by meteorologists to house weather instruments, especially thermometers. It is a box made of wood or other materials with slatted sides, allowing air to circulate freely while shielding the instruments from direct sunlight, rain, and other environmental factors that might affect readings. Its design helps ensure accurate and consistent measurements of temperature and humidity. The Stevenson Screen is often painted white to reflect sunlight and is positioned at a standard height above the ground for standardized data collection. It plays a crucial role in ensuring that weather data is reliable and comparable over time and location.
