From the article:
Tree rings have long been recognized as a useful proxy for past climate variations because of their special characteristics, such as precise dating, annual resolution, long time series, and climate sensitivity. The International Tree-Ring Data Bank (ITRDB) archives a wealth of tree-ring records contributed by scientists around the world. However, the use of these data for reconstruction of a specific climate variable over a large geographical region is not a straightforward procedure.
