Bison Climate North America Over 21,000 Years

This document contains the location of the raster cells for all of North America in 1,000 years intervals going back 21,000. Each raster cell has the associated paleoclimate data matching climate variables of Worldclim for each of the 1,000 year intervals. There is also a column that identifies the 1,000 year interval and a column that represents the presence and absence of bison occurring in the raster grid cell during that interval. This data is used to build the presence-only climate envelope model.
