Aircraft Meteorological Data Reports (AMDAR) and Aircraft Communications Addressing and Reporting System (ACARS) Data
Summary
AMDAR is the generally-accepted worldwide term for automated weather reports from commercial aircraft. The contribution of the United States to AMDAR is called MDCRS. MDCRS is funded jointly by the U.S. government and the seven participating airlines (American, Delta, Federal Express, Northwest, Southwest, United, and United Parcel Service). These U.S. data are also sometimes called ACARS.
