Wikimedia Commons has a large collection of Köppen climate classification maps in its Category:Köppen-Geiger. For example, Russia, Canada, or USA. The formats available on Wikimedia Commons are (mostly) PNG and SVG, which are not georeferenced. Is there any public source of Köppen climate classification maps in georeferenced formats, such as geotiff, so that I can load it into GIS software and combine it with other maps?
This would make it much easier to tell, for example, what part of British Columbia has BSk.
