The gridded climate layers downloadable below are in Lambert Azimuthal Equal-Area projection, at 1km resolution, and covering North America.
The rasters are provided in the GeoTIFF format, a non-proprietary format
which is compatible with most GIS applications. The individual rasters are ~30MB
in size, and each zipfile (which contains a group of rasters) is about 1GB in
size.
Two sets of variables are available for download. One consists of 33 biologically relevant variables, including seasonal and annual means, extremes, growing and chilling degree days, snow fall, potential evapotranspiration, and a number of drought indices. The second dataset consists of 48 monthly temperature and precipitation variables. See the metadata for complete description of variables.
These data are made available under a CC-BY 4.0 license. This license allows users to distribute, remix, adapt, and build upon the material in any medium or format, so long as attribution is given to the creator.

Selecting scenarios for climate change impact and adaptation research is a complex task. We selected nine individual models to represent all major clusters of similar AOGCMs, as shown in the dendrogram below. A broader set of 13 AOGCMs were used to create the ensemble data. Ensemble projections are also provided here for a greater range of time periods and scenarios than are the projections from individual AOGCMs. We encourage you to explore further the commonalities and contrasts between projections from different AOGCMs using this web app developed by Colin Mahony of the BC Ministry of Forests, Lands, Natural Resource Operations and Rural Development.
Click here to see a high resolution version of the dendrogram and array of thumbnails showing change in precipitation, mean daily maximum temperature, and mean daily minimum temperature for North America for 13 AOGCMS and the ensemble.
