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 a tree. As well as dating them, this can give data for dendroclimatology , the study of climate and atmospheric conditions during different periods in history from the wood of old trees.
The utility of tree-ring dating in an environmental sense is the most applicable of the three in today's world. Tree rings can be used to reconstruct numerous environmental variables such as temperature, precipitation, stream flow, drought society, fire frequency and intensity, insect infestation, atmospheric circulation patterns, among others.

Dendropyrochronology is the science of using tree-ring dating to study and reconstruct the history of wild fires. It is a subfield of dendrochronology, along with dendroclimatology and dendroarchaeology. [1] [2] [3]
Incremental dating techniques allow the construction of year-by-year annual chronologies, which can be temporally fixed (i.e., linked to the present day and thus calendar or sidereal time) or floating. Archaeologists use tree-ring dating (dendrochronology) to determine the age of old pieces of wood. Trees usually add growth rings on a yearly ...
Variation of tree ring width translated into summer temperature anomalies for the past 7000 years, based on samples from holocene deposits on Yamal Peninsula and Siberian now living conifers. [ 1 ] Dendroclimatology is the science of determining past climates from trees (primarily properties of the annual tree rings ).

Michael G. L. Baillie (1944-2023) was a leading expert in dendrochronology, or dating by means of tree-rings, and Professor of Palaeoecology at Queen's University of Belfast, in Northern Ireland. In the 1980s, he was instrumental in building a year-by-year chronology of tree-ring growth reaching 7,400 years into the past.
Dating methods are crucial to the process of understanding the archaeological record. Dating methods encompass both Relative dating and Absolute dating methods, as well as the interpretation of archaeological context and sequence. Many disciplines of archaeological science are concerned with dating evidence.
