The residual chronology of radial and height growth of the 150 (A) and 50-year-old Scots pine (B). Height-growth chronologies lagged by one year. Ratio of height and radial-growth residual chronologies of the 150-year-old Scots pine from 1845 to 1954 (A) and of the both (50 and 150-year-old) stands from 1955 to 2004 (B). Summer temperature index (June-August temperature weighted by July temperature and scaled to 0.0-1.0) is presented as a bar chart.
