Where is the world's largest known tree ring archive used in climate science?
Quick Answer
Major tree-ring archives are kept in research centers and museums around the world, with famous collections in the United States and Europe. The data often come from ancient bristlecone pines and other long-lived trees.
The Full Story
Tree-ring archives, also called dendrochronology collections, are stored in research institutions in places such as the United States and Europe. Scientists build these archives from wood samples taken from living trees, dead wood, and archaeological timbers. One of the most important sources of long climate records is the bristlecone pine region of the western United States. These records help researchers date events, reconstruct past rainfall, and study long-term climate change.
