CanHomW: Canadian Homogenized Wind Speed Data, 1953-2023

Canadian Homogenized Wind Speed (CanHomW V2) datasets contain homogenized monthly and daily mean wind speed series from 154 long-term stations across Canada for the period 1953-2023. The data was produced by Environment and Climate Change Canada using a modified quantile matching adjustment method without a reference series, as detailed in Wang et al. (2025). The datasets include both raw and homogenized data series for transparency and are intended for trend assessment.

Use Cases

• Assessing long-term wind speed trends based on homogenized monthly and daily data series.
• Validating climate reanalysis products like the Twentieth Century Reanalysis using the included reference series comparisons.
• Studying the impact of data homogenization techniques on climate records using the provided raw and adjusted data.

Strengths

• Covers a 71-year time range from 1953 to 2023.
• Includes data from 154 long-term stations across Canada.
• Provides both monthly and daily temporal resolutions.
• Includes raw data alongside homogenized series for traceability.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• The density of long-term stations is described as low, which may limit spatial representativeness.
• Row count is unknown, which may limit suitability assessment.
