Automated Surface Observing Systems monitor weather conditions at many airports.Measuring surface air temperature at U.S.More precise thermometers measure air temperature by checking how much electricity can pass through a sample of pure metal. The most common type of thermometer is the liquid-in-glass thermometer. Thermometers, shielded from direct solar energy, are used to measure surface air 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.
