Canadian Monthly Snowfall and Depth Records 1943-1982

Monthly snowfall and end-of-month snow depth measurements from 140 weather stations across Canada, spanning 1943 to 1982. Data originates from the Atmospheric Environment Service Canadian Climate Centre and NOAA's National Climatic Data Center, curated by NASA. Records are organized into eight regional files, each containing stations with a minimum of 20 years of observations.

Use Cases

• Analyzing regional snowfall trends over four decades using monthly total snowfall (millimeters) measurements.
• Modeling snowpack persistence by examining end-of-month snow depth (centimeters) records.
• Conducting spatial comparisons of snow accumulation across Canadian provinces and territories using station latitude and longitude.
• Validating climate model outputs for solid precipitation against historical station data.

Strengths

• Contains data from 140 stations selected for having at least 20 years of continuous records, ensuring temporal consistency.
• Provides precise station location data with latitude and longitude specified to hundredths of a degree.
• Covers a 40-year time range (1943-1982) for long-term climate trend analysis.

Limitations

• The exact row count and dataset size are not specified on any platform.
• Conflicting last updated dates: datagov lists 2026-03-12, while nasa_earthdata lists 1982-12-31.
• Data is historical, ending in 1982, and does not include recent decades.
