Predicting spatial variability of climate from tree-rings

I would like to draw your attention to our recent publication:

del Castillo J, Aguilera M, Voltas J, Ferrio JP (2013) Isoscapes of tree-ring carbon-13 perform like meteorological networks in predicting regional precipitation patterns. Journal of Geophysical Research Biogeosciences 118, 352-360

In this work, we managed to model spatial variability in mean annual precipitation from isotope data in a network of tree-ring sampling sites. Interestingly, the predictive ability of the models was almost identical to that obtained using a network of meteorological data with similar spatial density. This opens the possibility to upscale tree-ring reconstructions from local to regional levels.

Looking forward to getting your comments and suggestions about this study.
