425 homogenized monthly and daily precipitation series for stations across Canada, developed for climate trend analysis. The dataset was created by Environment and Climate Change Canada and includes key improvements over Version 1, such as expanded source data and enhanced quality control. It was last updated on July 14, 2026.
Use Cases
- Analyze long-term precipitation trends based on homogenized monthly series.
- Study daily precipitation variability and extremes based on consistent daily totals.
- Validate climate models using adjusted data from automated gauge stations.
- Investigate non-climatic shifts in precipitation records using enhanced changepoint detection methods.
Strengths
- Includes data for 425 stations across Canada.
- Enhanced changepoint detection includes tests on untransformed and log-transformed data.
- Incorporates adjusted data from automated gauge stations and the CoCoRaHS network for recent decades.
Limitations
- Row count is unknown, which may limit suitability assessment.
- Column-level documentation is absent; field semantics must be inferred after download.
