There are no studies on cork ring width variation in the first periderm, but the visual observation of stem discs with virgin cork show a decrease of ring width especially after around 20 years of age.

At the same time, this chronology is probably the longest absolutely dated and annually resolved temperature proxy record.

Sample collection has been made in intensive collaboration with the Finnish Forest Research Institute and SAIMA Centre for Environmental Sciences.

how cork ring width varies in the successive periderms during the tree life.

Again no systematic studies are available and the existing data refers to singular cases, as that represented in for one tree where the thickness of the cork layer is plotted for successive 10-year periderms.
