What should the observer do if visibility is consistently low during observations?

When visibility is consistently low during observations, it is important for the observer to report as per current observations regardless of consistency. This approach ensures that the data reflects real-time and accurate atmospheric conditions at the moment of observation.

Meteorological observations are designed to capture current weather conditions to provide the most precise information for forecasting and safety. Reporting what is observed allows for immediate and actionable insights for users of the data, such as pilots, mariners, and emergency responders, who rely on up-to-date visibility assessments for their operations.

This practice upholds the integrity of meteorological data collection and standardizes how consistently low visibility is managed in reporting, fostering a better understanding of prevailing conditions. In contrast, basing reports on averages from past records or relying on personal judgment may introduce variability or subjectivity that undermines the reliability of the data.
