    • n exposure In meteorology, the method of placing any instrument so that it shall correctly measure a given meteorological element. A barometer should he so placed as to indicate the pressure prevailing in the free air at a given level. If the wind is blowing the instrument, or the house in which it is placed, becomes an obstacle to the wind, by which the pressure is increased on the windward and diminished on the leeward side; similarly, in a wind, an open chimney in a closed room causes a lowering of the pressure, while a window opened on the windward side causes an increase. In general, a barometer, whether mercurial or aneroid. should be so placed that the wind-effect may be annulled or measured and allowed for. The latter is accomplished by the anemobarometer (which see). In order that a thermometer shall indicate truly the temperature of the air, it must receive heat from the air by convection and conduction, but all radiation from other objects should be cut off except from those having the same temperature as the air. When a thermometer is hung in the open air in the shade, it is usually exposed to radiant heat from the soil, buildings, and clouds, and to reflections of the rays of the sun; it also radiates its own heat to cold objects and to the sky. Its temperature represents a balance between its momentary gain and loss of heat, and has little to do with the temperature of the adjacent air unless the wind is blowing strongly enough. When held in the shadow of a wall or tree, its temperature is usually somewhat lower than when it is moved a few inches farther on into the full sunshine, although the temperature of the air is the same in both places. A common method of exposure is to place the thermometer within a screen or so-called thermometer-shelter made of light slats overlapping each other so as to cut out direct sunlight but allow the free entrance of the wind. This method fails if the wind fails to keep the interior surfaces of the shelter at the true air-temperature, for, in general, the temperature of these surfaces lags behind the temperature of the air. By rapidly whirling a thermometer or by creating a rapid current past it, the convection may be increased to such an extent as to bring the thermometer to the temperature of the air within a very small limit. Numerous methods of effecting this have been devised and employed.
