Today, the AMDAR system facilitates the fully automated collection and transmission of weather observations from commercial aircraft, as well as some military and private aircraft. The primary dataset from each aircraft participating in the AMDAR programme includes position in time and space, wind speed and direction, and ambient temperature. AMDAR data are used operationally to support a wide range of meteorological applications and are considered by WMO to be an essential source of basic upper-air information. Some aircraft also provide information on moisture, turbulence and ice accretion.
