Trend of Total Precipitation for 1948-2012 based on Canadian gridded data

Trend of Total Precipitation for 1948-2012 based on Canadian gridded data is an open dataset from Environment and Climate Change Canada with 9 files (HTML, PDF); catalogue record updated 2026-09-01. On CanQuery you can follow the original downloads. Files are available in English and French.

Seasonal and annual trends of relative total precipitation change (%) for 1948-2012 based on Canadian gridded data (CANGRD) are available, at a 50km resolution across Canada. The relative trends reflect the percent change in total precipitation over a period from the baseline value (defined as the average over 1961-1990 as the reference period). CANGRD data are interpolated from adjusted and homogenized climate station data (i.e., AHCCD datasets). Adjusted precipitation data incorporate adjustments to the original station data to account for discontinuities from non-climatic factors, such as instrument changes or station relocation.
