Solution Verified by Toppr Correct option is B) Stevenson's Screen is used to shield meteorological instruments from precipitation and direct external radiations, such as heat. The screen is louvered to allow air to circulate around the instruments. Additionally, the screen is painted white to reflect the sun's direct rays. The Stevenson Screen or thermometer screen is a standard shelter (from rain, snow and high winds, but also leaves and animals) for meteorological instruments, particularly wet and dry bulb thermometers used to record humidity and air temperature. It is kept 1.25m/4.1ft (UK standard) above the ground by legs to avoid strong temperature gradients at ground level, has louvred sides to encourage. Each Stevenson Screen and the air temperature reference sensor are fitted with matched, calibrated thermistors, NIST traceable with certificates, that are connected to a calibrated data-logger, also with a certificate. The resolution is .01 degree Fahrenheit with an accuracy of +/- 0.1 degree over the range. Answer - It is made of wood to avoid absorption of heat. - The sides of a Stevenson screen is louvered to allow free circulation of Air. - It has double roof to prevent the sun's heat from reaching the inside of the screen. - It is painted white so as to reflect sunshine and heat.

The following are some of the prominent features of the Stevenson screen. It is painted white in order to reflect excessive heat. It is 1.2 meters above the ground to avoid ground weather conditions from affecting the readings yielded by the housed instruments. It has louvered sides to allow for the free circulation of air. Why is the Stevenson screen painted white? to reflect incoming solar radiation. Why does the stevenson screen have double roofing. to protect the instruments from precipitation. Rain could affect temperature or humidity readings. Which way does the door of the stevenson screen always face. The Stevenson Screen or thermometer screen is a standard shelter (from rain, snow and high winds, but also leaves and animals) for meteorological instruments, particularly wet and dry bulb thermometers used to record humidity and air temperature. It is kept 1.25m/4.1ft (UK standard) above the ground by legs to avoid strong temperature gradients at ground level, has louvred sides to encourage. Search for: 'Stevenson screen' in Oxford Reference ». A widely used shelter that contains meteorological instruments, arranged in such a way that they give standard readings. The screen consists of a box, with sides ventilated by louvres, a ventilated floor and upper part, and an air space between an inner and outer roof. The box contains.
Why Is Stevenson Screen Painted White PAINTYU
The traditional Stevenson Screen is a box shape, constructed of wood, in a double-louvered design. However, it is possible to construct a screen using other materials and shapes, such as a pyramid.. The whole screen is painted with several coats of white to reflect sunlight radiation and will usually require repainting every two years. Siting. Why Stevenson screen is painted white? Stevenson screens are always painted white to better reflect the sun's rays. The louvered sides allow outside air to flow around the thermometers. Stevenson screens are always installed so that the door opens facing north, to keep the sun from shining directly on the thermometers and affecting the readings.
Why is it painted white in color ? It is painted white to reflect the incoming solar radiation Why is it made of wood It is made of wood to reduce excessive heat Why is it fitted with louvres It is fitted with louvres to allow circulation /flow through easily Why does is have a doubled roof To prevent rain from entering it A Stevenson screen (also known as an instrument shelter) is a meteorological screen to shield instruments against precipitation and direct heat radiation from outside sources, while still allowing air to circulate freely around them. Why do we place thermometer in shelters that are painted white?
Irrigation and paint as reasons for a cooling bias
Stevenson's Screen is a wooden box fitted into a steel frame, specially designed to protect weather instruments like thermometer, barometer, etc. from the sun's rays and other natural heat radiation.. It is painted white to reflect incoming radiation from the sun and is set at a height of 1.25 m above the ground, so as not to be affected. The Stevenson Screen is a double-louvered wooden box, painted white and specially designed to shield the thermometers from the direct rays of the sun, from precipitation, and from heat radiation from the ground. The louvered construction allows the free flow of air over the thermometer bulbs. So that meaningful comparisons can be made with.
