Element Analytics
Statistics listed below are provided as a guide to determine the validity of Normals and Extremes calculations. For example, a composite station with 30 years of record between 1991 and 2020 with no missing years would be a more reliable normal than a composite station with 15 years of record and 2 missing years. Less than 100% possible observations indicates that out of the total number of observations used, some records were missing.

Composite Metadata / Threads
The Climate Normals, Averages, and Extremes are based on Canadian climate composite stations with at least 15 years of data between 1991 and 2020. Composite stations are comprised of one or more stations operated by the Meteorological Service of Canada (MSC) or its partners, where data from individual stations are joined together to create a 30-year data series for a given location. All stations (and associated metadata) used as part of the composite are listed below, alongside the threads used to calculate each Normals/Extremes element.

Composite Station Threads
Station composites are threaded from the beginning of the Normals period starting in 1991 to the end of 2020, where the predecessor site's data is used until the end of its period of record and is then joined to the current operating site to extend the time series. Threads are generated by climate element for hourly and daily data, and may vary due to differences in station history, instrumentation, meteorological data availability, data quality, or proximity. Normals and Extremes elements are grouped based on the climate element used in its calculation. For long-term extremes (LTE), the same Normals period threads are extended back in time to the earliest date of data available from the first station used in the data series. These use the LTE Start Date instead of the Start Date, that applies to normals period elements.
For additional station metadata information, refer to the above section "Composite Station Metadata".
