What is the difference between radiocarbon dating and dendrochronology

It is also used in radiocarbon dating to calibrate radiocarbon ages.New growth in trees occurs in a layer of cells near the bark.A tree's growth rate changes in a predictable pattern throughout the year in response to seasonal climate changes, resulting in visible growth rings.

Because of that precision, dendrochronology is used to calibrate ​radiocarbon dating, by giving science a measure of the atmospheric conditions which are known to cause radiocarbon dates to vary.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.In his Trattato della Pittura (Treatise on Painting), Leonardo da Vinci was the first person to mention that trees form rings annually and that their thickness is determined by the conditions under which they grew. 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.

AMS dating is an advanced method compared to radiometric analysis using liquid scintillation counters (LSC). Samples submitted for radiometric dating will be reported as Radiometric PLUS, which combines large sample handling techniques with particle detection.
