What: Development of spatial datasets representing 30-year (1991–2020) average monthly total precipitation and minimum/maximum temperature for Canada and the United States. These high-resolution (~2 km) datasets were generated using observed climate data from Environment and Climate Change Canada (ECCC) and the National Oceanic and Atmospheric Administration (NOAA), interpolated with thin-plate spline models to produce seamless geospatial grids.
Why: These datasets provide a standardized climate baseline, supporting hydrological modelling, climate change assessments, and resource management. By offering long-term averages of key climate variables, they enable researchers, policymakers, and industry professionals to analyze regional climate patterns, assess trends, and inform decision-making in sectors such as agriculture, water resource planning, and infrastructure resilience.
