Growth trend detection. (a) Example of TRW changes over the last century for the cohort of age 26–50 yrs. and fitted polynomial trend (every dot in the scatterplot represents the mean RW of one individual between 26 and 50 years of cambial age); (b) Trend-lines like in a) for all age-cohorts from age 1–25 until age 201–225, shifted one year and plotted with respect to their average TRW in 1890 and (c) Mean trend (relative to pre-1890 growth rates) from all age cohorts in b) with standard deviation (grey shading); this curve (right axis) was used to pre-detrend the raw TRW dataset in order to remove human induced non-climatic (fertilization) trends.
