Review on Atmospheric Pressure Monitoring

Abstract

Surface pressure measurements are
traditionally compensated for pressure
change with height against the backdrop of a
challenging but common measurement. The
station pressure is the pressure observed
without compensation for height, whereas the
pressure at sea level is calibrated to the
internationally accepted sea level datum.
Instruments for detecting atmospheric
pressure have traditionally been divided into
two sorts based on whether or not the sensing
element is a liquid (usually mercury) (aneroid
barometers). The pressure measured by a
barometer is usually adjusted to sea level for
everyday use. Furthermore, atmospheric
pressure is a fundamental atmospheric
variable; the impact of flow around a
building will induce local pressure variations,
which might occasionally jeopardize an
accurate barometer measurement. An
aneroid barometer measures atmospheric
pressure by using one or more hollow,
partially evacuated, corrugated metal disks
held against collapse by an inside or outside
spring; the shape of the disk changes with
changing pressure and can be recorded using
a pen arm and a clock-driven revolving drum.
