Aircraft Reports

Aircraft reports are reports of actual weather conditions encountered by weather while in flight. The information is typically transmitted by radio to a ground station.

U.S. air carriers are generally the only aircraft to transmit voice Pilot Reports via National Weather Service communication circuits. Therefore, there are rarely PIREPs outside of the continental U.S. and the immediate coastal regions. There are some Canadian and Alaskan PIREPs but almost no Mexican reports. There are oceanic AIREPs in the database which include temperature and wind data.
