Resumen:
In South America (SA) several documentary based
climate time series exist, some of them extending back to the
16th century.Most of these records end in the 19th century, and
can not be calibrated against instrumental data. Here, we used
the newspaper Los Andes from Mendoza, Argentina, to
extend documentary based indices of Mendoza precipitation
and Central Andes snow depth to the late 20th century. A
statistical approach to create pseudo documentary 20th
century data was applied to prolong eight other documentary
records. Increased variability of the hydrological cycle in the
Central Andes and prevailing periods of wet and dry years in
Mendoza suggest that the 20th century is extraordinary in the
context of the last 400 years. The final set of extended
documentaries explains significant portions of SA
precipitation variability in large areas between 20S and
40S and can therefore improve the network of annually
resolved precipitation proxies.S and
