<P> Dendrochronology ( or tree - ring dating ) is the scientific method of dating tree rings ( also called growth rings ) to the exact year they were formed in order to analyze atmospheric conditions during different periods in history . Dendrochronology is useful for determining the timing of events and rates of change in the environment ( most prominently climate ) and also in works of art and architecture , such as old panel paintings on wood , buildings , etc . It is also used in radiocarbon dating to calibrate radiocarbon ages . </P>
