Note: Barometric air pressure is usually reported as "relative air
pressure". This reading is based on the combination of absolute air
pressure and altitude. In general, an increase in altitude will result in a
decrease in air pressure. Relative air pressure will make readings in
nearby locations relative to each other to allow for proper forecasting.
The absolute air pressure reading in the Weather Center cannot be
calibrated, only the relative air pressure.
