Temperature and Dew Point

Beauport CS, Que. has a weather station that reported reliably enough during the analysis period that we have included it in our network. When available, historical temperature and dew point measurements are taken directly from this weather station. These records are obtained from NOAA's Integrated Surface Hourly data set, falling back on ICAO METAR records as required.

In the case of missing or erroneous measurements from this station, we fall back on records from nearby stations, adjusted according to typical seasonal and diurnal intra-station differences. For a given day of the year and hour of the day, the fallback station is selected to minimize the prediction error over the years for which there are measurements for both stations.

The stations on which we may fall back include but are not limited to Ste Foy CS , Que.; Quebec / Jean Lesage International; Jean Lesage International Airport; CFB Valcartier; Ile D'Orleans Automated Reporting Station; Cap Tourmente; Foret Montmorency Rcs; and Charlevoix CS , Que..
