How often is ASOS published?

ASOS, or Automated Surface Observing System, publishes weather data once every minute. This frequency allows for near-real-time updates on weather conditions, including temperature, wind speed, precipitation, and visibility. The continuous monitoring and reporting from ASOS systems are crucial for aviation, meteorological research, and severe weather warnings, providing timely information that helps ensure safety and operational efficiency.

Other frequencies, such as once per hour or every 30 minutes, would not capture rapid changes in weather conditions, making them less effective for real-time scenarios. Therefore, the one-minute frequency of ASOS is specifically designed to deliver the most up-to-date weather information possible.
