Data access
Originally accessible to download from Dryad:
Karger, D.N., Conrad, O., Böhner, J., Kawohl, T., Kreft, H., Soria-Auza, R.W., Zimmermann, N.E., Linder, H.P., Kessler, M. (2017) Data from: Climatologies at high resolution for the earth’s land surface areas. Dryad Digital Repository. https://doi.org/10.5061/dryad.kd1d4
On February 2021 the recommended method is to use the download server.
Once in the server, is easy to select the files needed, and download a list of files paths for download with several tools. Here I use wget
