Dendroclimatology is a subfield of dendrochronology that utilizes the properties of the annual tree rings to determine past climates. In other words, dendroclimatology uses dated and annually resolved growth rings of trees to reconstruct and analyze past climatic variations. Generally, when environmental conditions are favourable, tree rings become wider. They become narrower when the conditions are not favourable. Moreover, total ring width, earlywood/latewood, wood density of rings are also taken into consideration in dendroclimatology.

Besides, the annual growth of trees may be affected by microclimate: sunshine, precipitation, temperature, wind speed, and humidity. Moreover, the light-coloured rings represent woods grown in the spring and early summer while the dark rings represent woods grown the late summer and fall. Scientists have estimated the local climates for many years using tree rings. Furthermore, they have even estimated the past regional and global climates using the information of multiple tree ring studies. The crucial steps of dendroclimatology are the site selection and accurate dating of each tree ring to its year of formation.
What are the Similarities Between Dendrochronology and Dendroclimatology?
Dendroclimatology is a branch of dendrochronology.
Both fields utilize annual growth rings of trees and timber.
They are useful to determine past climatic variations.
Moreover, the age of the tree can be determined in these studies.
What is the Difference Between Dendrochronology and Dendroclimatology?
Dendrochronology is the study of annual growth rings of trees while dendroclimatology is the use of annual growth tree rings to determine past climatic variations. Therefore, the key difference between dendrochronology and dendroclimatology is that dendrochronology studies annual growth rings of trees, while dendroclimatology studies the relationships between annual growth rings of trees and past climate conditions or variations.
Summary – Dendrochronology vs Dendroclimatology
In summarizing the difference between dendrochronology and dendroclimatology, dendrochronology is the study of annual growth rings of trees while dendroclimatology is the study of the relationships between annual growth rings of trees and past climate conditions or variations. Therefore, dendroclimatology can be used to reconstruct some information about past environmental conditions since trees are sensitive to climate changes or conditions.
