Height above mean sea level (AMSL) is the elevation (on the ground) or altitude (in the air) of an object, relative to a reference datum for mean sea level (MSL). It is also used in aviation, where some heights are recorded and reported with respect to mean sea level (contrast with flight level ), and in the atmospheric sciences , and in land ...
Height above mean sea level is a measure of a location's vertical distance (height, elevation or altitude) in reference to a vertical datum based on a historic mean sea level. In geodesy, it is formalized as orthometric height. The zero level varies in different countries due to different reference points and historic measurement periods.
This is as opposed to altitude/elevation above mean sea level (AMSL), or (in broadcast engineering) height above average terrain (HAAT). In other words, these expressions (AGL, AMSL, HAAT) indicate where the "zero level" or "reference altitude" is located.
AMSL is an acronym for "Above Mean Sea Level", the elevation of a location above a standardized sea level. AMSL may also refer to: Alberta Major Soccer League, a Canadian soccer league; Airbus Military Sociedad Limitada, a former aerospace company based in Spain; Aéroport Montréal Saint-Hubert Longueuil, a Canadian airport
QNH - is the barometric altimeter setting that causes an altimeter to read aircraft elevation above mean sea level - altitude (AMSL - above mean sea level) in ISA temperature conditions in the vicinity of the airfield that reported the QNH value.
