If your station fails QC you will receive a notice by email, or on our site messaging system. Your data will still be saved in our databases, however, it will not be shown in the normal places on the site such as city pages and the WunderMap.
Possible reasons for QC failure:
+ weather data values outside of normal range. (eg, your temperature is > 150 F or < -150 F)
+ weather data values changing at too slow or too fast a rate. (eg, your temperature changes from -10 F to 70 F in a few minutes or your temperature never changes over a 24 hour period)
+ weather data values do not agree with stations nearby. (eg, your temperature is 70 F while every station nearby is less than 32 F)
If your station begins report good data again, the station will automatically be removed from failure status.
If you feel your station's data is good, and that our QC algorithm is in error, please contact firstname.lastname@example.org.
