What does a bracket next to a sky coverage symbol imply?

A bracket next to a sky coverage symbol signifies that the data provided is automated. This notation helps users quickly distinguish between information collected through human observation and data generated by automated systems. Automated reports may include weather conditions gathered from sensors and other technological means, which can enhance the efficiency and timeliness of weather reporting.

Understanding this distinction is important for interpreting weather data accurately, especially in situations where the reliability of information matters. Automated data can be particularly beneficial for real-time decision-making, whereas visual observations may vary based on the observer’s location and conditions at the time of observation. Recognizing the nature of the data source allows users to gauge how they should interpret the sky coverage information in the context of overall weather assessments.
