Above mean sea level (AMSL) is the elevation (on the ground) or altitude (in the air) of any object, relative to the average sea level datum. AMSL is used extensively in radio (both in broadcasting and other telecommunications uses) by engineers to determine the coverage area a station will be able to reach. It is also used in aviation, where some heights are recorded and reported with respect to AMSL (contrast with flight level), and in the atmospheric sciences.
