Pressure Readings
Absolute Barometric Pressure Number
Barometric pressure is read by the forecast station. The numeric pressure value adjusts automatically as the
forecast station reads changes in air pressure. Since this number is absolute pressure, it may not be the same
as a local reporting station that reads in relative pressure.
Note: The number cannot be calibrated.
 Absolute Pressure is measured in a vacuum without the influences of terrain, weather, water, foliage and
elevation. The air pressure it would be consistent at every elevation and decrease as it went higher.
 Relative Pressure is a combination of air pressure and altitude. Relative air pressure will make readings in
local areas relative to each other to allow for proper forecasting.
