I plagiarized this from a 2017 post regarding goldstars / I have one by-the-way
Directly from the WU web site
Are you a quality gold star weather station?
← Personal Weather Stations
How can I tell what stations have high quality data?
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
