Key facts
Contents & fields
The dataset comprises three sub-datasets: daily precipitation (ANUSPLIN-AdjPdly, since 1900), pentad average precipitation rate (ANUSPLIN-AdjP5d, since 1950), and monthly total precipitation (ANUSPLIN-AdjPmly, since 1872), all on a 0.083333°×0.083333° grid. Data are generated from ANUSPLIN surfaces; daily data are based on the Adjusted Daily Rainfall and Snowfall dataset version 2016 (3346 stations). No field-level description is provided on the source page.
Research uses
Suitable for Canadian regional precipitation climatology, hydrological modeling, and agricultural meteorology. Note that the data are not homogenized; homogeneity testing is required before trend analysis.

Why this is hard to get on your own
When obtaining high-resolution gridded adjusted precipitation data for Canada, one often needs to distinguish different time scales (daily/pentad/monthly) and note early northern data gaps and the lack of homogenization.
