This dataset covers the last 120k years, at intervals of 1/2 k years, and a resolution of 0.5 degrees in latitude and longitude.

If you use this dataset, make sure to cite the original publication:
Beyer, R.M., Krapp, M. & Manica, A. High-resolution terrestrial climate, bioclimate and vegetation for the last 120,000 years. Sci Data 7, 236 (2020). doi:10.1038/s41597-020-0552-1
The version included in pastclim has the ice sheets masked, as well as
internal seas (Black and Caspian Sea) removed. The latter are based on:

As there is no reconstruction of their depth through time, modern outlines were used for all time steps.
Also, for bio15, the coefficient of variation was computed after adding one to monthly estimates, and it was multiplied by 100 following https://pubs.usgs.gov/ds/691/ds691.pdf
Changelog
