CanGridP mlyV2: Canadian Monthly Precipitation Grids

CanGridP mlyV2 provides high-resolution gridded monthly precipitation amounts for Canada, based on homogenized station observations. The dataset is produced by Environment and Climate Change Canada using ordinary kriging on data from 425 stations. It was last updated in July 2026.

Use Cases

• Validate climate models based on homogenized precipitation data.
• Assess long-term precipitation trends across Canada.
• Perform downscaling studies using the high-resolution gridded data.
• Monitor climate changes using the consistent monthly series.

Strengths

• Based on homogenized data from 425 stations across Canada.
• High-resolution gridded data on an approximately 10-km grid.
• Version 2 includes expanded source datasets and improved quality control procedures.
• Represents precipitation trends reasonably well since 1949 for Canada and since 1916 for southern Canada.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to station network coverage.
