Them there is terms used in Aviation Towely

QFE - Pressure measured at the station

QNH - QFE mathmatically reduced/increased to sea level using ISA std figures

QFF - QFE mathmatically reduced/increased to sea level using actual conditions (temperature)

QNE - Emergency pressure setting used for low pressure/high altitude operations. I.E. when the actual pressure setting is off the scale of the altimeter.
