This paper serves as foundational work and a first case study example of how one can evaluate key aspects of statistical downscaling method performance using a perfect model framework. The basic (and often overlooked) question being whether and to what extent statistical downscaling skill degrades when applied to future scenarios. The eye-opening (to some) answer illustrated by the case study presented in this journal article is, It can matter a lot, but also can vary geographically, seasonally, and with the amount of climate change being projected. And the differences can be large enough to alter conclusions being drawn for adaptation planning purposes.
