This dataset gives the tree-ring indices for Pinus
sylvestris at a site near Visdalen, Norway. The chronology
represents 34 dated series and spans the period between 1600 and
1983. The raw measurements were obtained from the ITRDB (see
source), and read in, detrended with cubic splines (frequency
cutoff of 50 percent at two thirds of the series length) and
averaged using read.rwl,
detrend, and chron from
package dplR.
