The highly waterdependent semiarid Andes of Chile and Argentina (CChA) are characterized by extremely variable annual precipitation regimes. The existing hydroclimate instrumental records from CChA provide a spatially dense network but only for the last 40-80 years. During recent decades our tree-ring studies in Austrocedrus chilensis have demonstrated the usefulness of this conifer to reconstruct hidroclimate variability in the CChA over several centuries. We will present a starting project were we propose to develop a millennium-long reconstructions of combined hydroclimate variables for the CChA. Our goals are to characterize the main temporal patterns of these reconstructions at different time-scales, and investigate the hindcast skill of downscaled climate products based on the current generation of General Circulation Models by comparing tree-ring based hydroclimatic reconstructions with simulated regional climates of the past millennium.
