What are the characteristics of Stevenson screen?
A Stevenson screen is a ventilation box used to house meteorological instruments, primarily thermometers and hygrometers. It is typically made of wood or synthetic materials and features slatted sides to allow for free air circulation while protecting instruments from direct sunlight and precipitation. The screen is painted white to reflect sunlight and minimize heat absorption. Its design ensures accurate temperature and humidity readings by maintaining a stable environment for the instruments inside.
Why stevenson screen placed in open area?
A Stevenson screen is placed in an open area to ensure accurate measurement of environmental conditions, particularly temperature and humidity. This location minimizes the influence of artificial heat sources, such as buildings or pavement, which can skew data. Additionally, being in an open space allows for unobstructed air circulation, promoting representative readings of the ambient atmospheric conditions. The screen's design, with its slatted sides, further facilitates ventilation while protecting instruments from direct sunlight and precipitation.
What is the function of air gaps in sides in Stevenson screen?
allows air to reach the thermometer so that it s temprature can be measured
Why was the Stevenson screen named after Thomas Stevenson?
he invented the instrument
What instruments are stored in the stevenson screen?
thermometer
Why stevenson screen is called a screen?
The Stevenson screen is called a "screen" because it serves to shield meteorological instruments from direct sunlight, precipitation, and wind, ensuring accurate temperature and humidity readings. Its design, typically featuring slatted sides and a white exterior, promotes air circulation while minimizing the influence of external environmental factors. This protective function is essential for maintaining the integrity of the data collected by instruments housed inside.
Why are the sides of the 'stevenson screen' louvered?
The sides of a Stevenson screen are louvered to allow air to circulate freely around the temperature and humidity sensors inside. This design helps prevent the sun's direct rays from hitting the sensors and affecting the accuracy of the readings. The louvered sides also help to reduce the impact of thermal radiation on the inside of the screen.

What is Stevenson's Screen?
In observataries,the thermometers are kept in a wooden box with good ventilation and air movement.This box is called stevenson's screen
What are the main characteristics of a steveson screen?
A Stevenson screen is a white slatted wooden box with a double roof design, used to shield temperature and humidity sensors from direct sunlight and precipitation. Its key characteristics include proper ventilation to ensure accurate measurements, a standard size of about 30 cm in height, and a location placed 1.25 to 2 meters above the ground.
