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.
A Stevenson screen is typically found at weather stations to house temperature and humidity sensors. It is a white louvered box mounted on a stand about four feet off the ground to shield the sensors from direct sunlight and other weather elements, providing accurate readings.
