barometry
Measuring air pressure
Barometry is the measurement of atmospheric pressure, or the science and techniques involved in such measurement.
The term appears mainly in technical contexts discussing weather instrumentation or laboratory procedures: The station's barometry equipment needed recalibration after the storm.
