Below is a checklist of Stevenson screens (weather instrument shelters) on postal items (stamps, souvenir sheets, aerogrammes, postal cards, etc.). Catalog numbers, years of issue, and notes on the items featured are given when available. If readers know of additional information or images, please contact the authors using the e-mail addresses at the bottom of this page.
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. It forms part of a standard weather station. The screen creates, as near possible, a uniform environment in relation to the air outside, and is used to shelter various types of temperature and humidity measuring instruments. The smallest screens contain a dry bulb thermometer and a wet bulb thermometer. Larger screens also include minimum and maximum thermometers. Still-larger screens can contain recording instruments: a thermograph and/or a hygrograph, or a thermohygrograph which combines the functions of those two instruments.
The Stevenson screen was designed by Thomas Stevenson (1818-1887), a British civil engineer and father of the author Robert Louis Stevenson. All screens should be installed so that the sensitive parts of all sensors are at the same level, at 1.5 meters above the ground. Exceptions to this may be made in an area subject to accumulations of snow. The shelter should be movable or, if this is impractical, be mounted at a level above the highest expected accumulation of snow for that location. Meteorological screens that do not fit the specifications for Stevenson screens (directly above) are identified below as instrument shelters.
Items that represent traditional land observing sites with multiple instruments (in an open area not too close to any buildings or trees or other obstacles, with at least one Stevenson screen and at least one other type of instrument) are highlighted in pale yellow in the table below.
