The document discusses weather data collection from commercial aircraft, known as AMDAR. It provides details on the current AMDAR program, including participating airlines and aircraft, the types of weather sensors used, and typical numbers of observations collected daily. It also outlines plans to expand AMDAR to additional aircraft and include water vapor sensors to improve coverage and support a variety of weather forecast needs.

- Selected aircraft were collecting atmospheric observations in the 1920’s, and only after this date did radiosondes commence operations in the 1950’s as the main in situ atmospheric observing system.

- AMDAR provide yet another means of comparing data from different upper air systems. AMDAR is frequently used by meteorologists to verify the initialization and performance of the numerical weather prediction models. It has also been used to flag erroneous radiosonde, profiler, and WSR-88D VAD winds, and to verify GOES and POES satellite soundings.
