Plain Language Summary

We summarize ongoing efforts at the Canadian Forest Service to produce spatial climate models for Canada and the United States. Our models, which encompass a wide range of variables and spatiotemporal extents, typically employ thin plate smoothing splines to interpolate and extrapolate climate station values as a function of latitude, longitude and elevation. The resulting surfaces can be resolved as grids (i.e., maps) or as point estimates at locations of interest. Recent efforts, detailed here include: updated models for the most recent 30-year normal period (i.e., 1981-2010), moisture balance models, future climate projections using the latest round of general circulation model (GCM) outputs and emissions scenarios, lake ice freeze/thaw models, and growing season models. These models are available to the Canadian forest community and beyond via the internet ( or by contacting the senior author.
