Alguém tem que explicar aos senhores do Wunderground o que são inversões térmicas. À bocado este aviso também aparecia na estação de Seiça, mas entretanto voltou ao normal.

Are personal weather stations on Weather Underground monitored for quality?
← Personal Weather Stations
Yes, we perform several quality control (QC) checks on incoming weather data observations to make sure we show accurate data on the site.
If your station fails QC, your data will still be saved in our databases but 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 reporting good data again, the station will automatically be removed from failure status and be added back to the maps and the site.
If you feel your station's data is good, and that our QC algorithm is in error, please contact [email protected].
