WebAir Temperature. Surface air temperature is the temperature of the air around us, generally measured at a height of around two meters (about 6 and a half feet) above the surface. Thermometers, shielded from direct solar energy, are used to measure surface air temperature. The most common type of thermometer is the liquid-in-glass thermometer. The temperature of the air near the surface of the Earth is measured at meteorological observatories and weather stations, usually using thermometers placed in a shelter such as a Stevenson screen, a standardized well-ventilated white-painted instrument shelter. The thermometers should be positioned 1.25–2 m above the ground. Details of this setup are defined by the World Meteorological Organization (WMO).
