The skill of the downscaling methods generally depended on reanalysis and
gridded observational dataset.
I prefer to use a reanalysis product as the base rather than
gridded observational datasets because the reanalysis product provides a dynamically consistent gridded state estimation that includes assimilation of available surface and satellite observations.

I note that both the
gridded model and
observational datasets used in our IJoC paper are freely available to researchers.
The simulations were evaluated using the spline - interpolated
dataset ANUSPLIN, a daily
observational gridded surface temperature and precipitation product with a nominal resolution of approximately 10 km.
