air/atmospheric pressure the force exerted on a surface by the air above it as gravity pulls it to Earth; measured with a barometer
barometer (mercury barometer (mm of mercury) measures air pressure; An instrument used especially in forecasting the weather and determining altitude where a column of mercury in a glass tube rises or falls as the weight of the atmosphere changes
aneroid barometer (millibar-MB) measure whether pressure is rising or falling, whether a high or low pressure system is coming or whether it is becoming more intense. Ex: altimeter, which measures altitude, or distance above sea level. barograph,
