What are the specifications for a Stevenson Screen?

A Stevenson Screen is a ventilated enclosure designed to protect meteorological instruments from direct sunlight and precipitation while allowing air to circulate freely. It is typically constructed from wood or metal, painted white to reflect heat, and features louvered sides for ventilation. The standard dimensions are approximately 1.2 meters high, 0.6 meters wide, and 0.6 meters deep, with a roof that is slanted to shed rain. The interior is often designed to hold thermometers and hygrometers at a standard height of 1.2 to 2 meters above ground level.
