A barometer measures what?

Explanation:
Barometers measure atmospheric pressure, the weight of the air surrounding us. This pressure changes with weather patterns, helping scientists predict storms or fair skies. Temperature is measured with a thermometer, humidity with a hygrometer, and wind speed with an anemometer, so those instruments track different properties. Since a barometer directly assesses the pressure of the air, it’s the instrument described by atmospheric pressure.
