S., Alexander Catlin Twining (1801–1884) suggested in 1833 that patterns among tree rings could be used to synchronize the dendrochronologies of various trees and thereby to reconstruct past climates across entire regions.

    During the latter half of the nineteenth century, the scientific study of tree rings and the application of dendrochronology began.

    Housed at the World Data Center-A (WDC-A) for Paleoclima tology at the National Geophysical Data Center in Boulder, Colorado, USA, the ITRDB currently contains 3275 tree-ring chronologies and 2804 tree-ring measurement data sets from over 1500 sites, contributed by 139 researchers worldwide.

    These data sets represent information from over 100 tree and shrub species.
