Which weather instrument is considered the standard for measuring atmospheric pressure?
Weather and ClimateWeather instruments
Quick Answer
The barometer is the standard instrument used to measure atmospheric pressure. Mercury and aneroid barometers have both played major roles in weather science.
The Full Story
A barometer is the classic instrument for measuring atmospheric pressure, one of the key variables in weather forecasting. Mercury barometers were historically used because changes in air pressure could be read from the height of a mercury column. Modern weather stations often use aneroid or electronic barometers for practicality and safety. Pressure trends help meteorologists identify storms, fair weather, and changing air masses.
