A ring-width chronology of Scots pine from northern Lapland covering the last two millennia

We have built a reliable ring-width chronology of Scots pine (Pinus sylvest ris L.) in northern Lapland, starting from the year 50 AD and covering the last two millennia. The chronology is built from 68 living trees and 274 de ad trees, collected between 68 degrees-70 degrees N and 21 degrees-30 degre es E. The bulk of the data from dead trees has been published previously. I n these earlier works the chronology was built without standardizing the se ries. We have now rebuilt the chronology using proper analytical tools. Thu s the interpretations have also been revised. Periods of enhanced and suppr essed pine growth in the northern timberline region during the last two mil lennia are presented. A comparison is also made between the northern chrono logy and a millennial chronology from southeastern Finland. Moreover we app ly means of measuring the strength of the common 'signal' in tree-ring chro nologies and chronology reliability as a function of time.
