All weather station data goes through a quality control (QC) process.
Each station is checked for
- Data Validity - Is the data within the valid range?
- Sensor Failure - Does you sensor appear stuck or repeat the same value throughout the day?
- Neighbor Check - Does your station agree with other nearby stations?
If your data passes all of these quality control (QC) checks, it will appear on our website and apps.
If you station is continuously passing our quality control process for 5 consecutive days, your station will be flagged as gold star.
You can tell whether your station is gold star by logging into your WU account on our website www.wunderground.com
Go to My Profile > My Weather Stations
If you are a gold star station you will see an gold icon next to your station.
The gold star icon also appears publicly on the PWS dashboard page. This allows you see see other stations of high quality.
