What kind of report does "AUTO" typically refer to in the context of automated observations?

In the context of automated observations, the term "AUTO" specifically refers to a report generated by an automated system. These automated reports, often from automated weather stations, provide real-time data on various weather parameters without the need for human intervention. This automation enhances the efficiency and frequency of data collection, making it easier to obtain timely weather information that is critical for flight operations and safety.

The nature of automated reports is such that they are direct outputs from machinery that continuously monitor environmental conditions, ensuring that the information is relayed quickly and accurately. This contrasts with reports requiring verification or manual input, as in the case of those certified by air traffic controllers or those that originate from manual weather observations. Automated reports are an essential tool for pilots and air traffic services, contributing to informed decision-making regarding flight operations.
