In-Filled Ontario Climate Records 1950-2005

339 monitoring stations provide fully in-filled precipitation and temperature records, addressing gaps from equipment failures. The Meteorological Service of Canada compiled this data, which is organized into eight Microsoft Access databases covering daily and hourly records from 1950 to 2005.

Use Cases

• Analyze long-term temperature trends using in-filled hourly and daily temperature records.
• Model regional precipitation patterns using the in-filled precipitation data from 339 stations.
• Validate climate models by comparing predictions against the gap-free historical records from 1950-2005.
• Study extreme weather events using the complete, in-filled time series for specific Ontario regions.

Strengths

• Data covers 56 years from 1950 to 2005, providing a long temporal baseline.
• Records from 339 monitoring stations offer spatial coverage across Ontario.
• In-filling process addresses missing records, creating a more complete time series.

Limitations

• Data format is legacy Microsoft Access, requiring specific software or conversion for modern analysis.
• Temporal coverage ends in 2005, lacking recent climate observations.
• Unknown sample size and specific column structure for the eight separate databases.
