How would I know if my weather station has passed the Weather Underground quality control process?
This is not a one-time certification. Stations are continually evaluated to The Weather Company (TWC) quality control standards. If they do not pass, they are removed from the TWC grid-based products. Weather stations can be re-added to the TWC grid after they meet quality control standards for 5 days in a row. At that time the weather station will be flagged as gold star.
