Summary

The datasets on this page have been developed by AdaptWest, a project funded by the Wilburforce Foundation to develop information resources for climate adaptation planning. The data are based on the Parameter Regression of Independent Slopes Model (PRISM) interpolation method for current climate, and the Coupled Model Intercomparison Project phase 5 (CMIP5) database corresponding to the 5th IPCC Assessment Report for future projections. Ensemble projectionjs are average projections from 15 CMIP5 models (CanESM2, ACCESS1.0, IPSL-CM5A-MR, MIROC5, MPI-ESM-LR, CCSM4, HadGEM2-ES, CNRM-CM5, CSIRO Mk 3.6, GFDL-CM3, INM-CM4, MRI-CGCM3, MIROC-ESM, CESM1-CAM5, GISS-E2R) that were chosen to represent all major clusters of similar AOGCMs (Knutti [...]

The data is available from adaptwest.databasin.org

The gridded climate layers downloadable below are in Lambert Conformal Conic projection, at 1km resolution, and covering North America. The database consists of 23 million grid cells and is designed to capture climate gradients, temperature inversions, and rain shadows in the landscape of North America.

There are two data formats available. NetCDF (.nc) files, a non-proprietary format, are compatible with most GIS applications. ASCII (.asc) files can be transformed to ESRI grids, a native format of ArcGIS software, but are also compatible with many other GIS applications.

Two sets of variables are available for download. One consists of 27 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.

All archives have been compressed with the 7-zip utilty. To extract the data, use the 7-zip software, which is freely available for Windows (link) as well as Mac and Linux systems (link). Use of 7-zip in place of the standard zip format allows better compression, lower storage costs, and shorter download times.
