Why does my absolute reference gauge show a different pressure than the local weather report or airport barometer?
Atmospheric pressure is affected by high and low pressure weather systems and how high the measuring station is above sea level. For weather barometer readings to make sense it is desirable to remove the effect of weather station altitude. A weather barometer reading is corrected to a hypothetical sea level reading by taking into account the altitude, pressure reading and temperature. An altimeter reading is corrected by taking into account the altitude and pressure reading. See the National Weather Service Handbook for more information and refer to Chapter 11 for details.
