Canadian Gridded Homogenized Monthly Precipitation (CanGridP mly)

The first version of this gridded dataset (on a 10-km EASE grid) of monthly total precipitation amounts was produced using a kriging-based gridding scheme to grid the Canadian homogenized monthly precipitation dataset CanHoPmlyV1 (Wang et al. 2023; available at https://open.canada.ca/data/dataset/1dd0c28e-2266-42e2-8985-2f47659e9d02). More specifically, ordinary kriging was used to grid the 1961-1990 climate normal values and the relative anomalies, separately; the resulting gridded datasets were used to produce this gridded dataset of monthly total precipitation amounts (Wang et al. 2023, Abbasnezhadi and Wang, 2024). As detailed in Wang et al. (2023), CanHomPmlyV1 is based on the quality-controlled version 2020 of the Adjusted Daily Rainfall and Snowfall (AdjDlyRS) dataset (Wang et al. 2017, available at https://open.canada.ca/data/en/dataset/d8616c52-a812-44ad-8754-7bcc0d8de305), and on daily total precipitation data from automated gauges (including Belfort, Fisher & Porter, Nipher, Geonor, and Pluvio), with some records from neighbouring stations being joined to form long-term data series.
