What code is present in the body of an automated METAR or SPECI report?

In an automated METAR or SPECI report, the code "AUTO" indicates that the report was generated automatically without human intervention. This designation is crucial for pilots and meteorologists, as it provides context about the reliability and accuracy of the data; automated reports typically rely on sensor inputs and predefined algorithms to compile weather information.

The presence of "AUTO" in the report signifies that the meteorological observations were made by automated equipment rather than human observers. This means that the report contains real-time data, which is essential for flight operations and weather assessments. Understanding this distinction helps users interpret the conditions reported and evaluate their implications for aviation safety.

The other codes, while relevant in different contexts, do not specifically indicate an automated report in the same way. "COR" refers to a corrected report, indicating that errors have been identified and rectified, while "MANUAL" signifies that the report was constructed by a human observer, which may involve subjective assessments, and "CHECK" does not correspond to standard METAR or SPECI report codes.
