conifersIP: Iberian Peninsula tree-ring width dataset

In DendroSync: A Set of Tools for Calculating Spatial Synchrony Between Tree-Ring Chronologies

Iberian Peninsula tree-ring width dataset

Description

This dataset presents tree-ring width chronologies of residual indices published in Shestakova et al. (2016). The dataset contains 30 tree-ring width chronologies of conifer species from the Iberian Peninsula for the period 1950-1999. Tree species are represented by Abies alba Mill., Pinus nigra subsp. salzmannii (Dunal) Franco and Pinus sylvestris L. The sampling sites are distributed across three subregions (north, centre and south) of the Iberian Peninsula. Site chronologies are obtained by cross-dating tree-ring width series and posterior detrending and autocorrelation removal with the Friedman supersmoother spline and autoregressive modeling.

Usage

data(conifersIP)

Format

A data.frame containing 30 tree-ring chronologies of residual indices for the period 1950-1999. The dataset includes three species (Abies alba, Pinus nigra, Pinus sylvestris) that are distributed across three regions (north, centre and south) in accordance with the latitudinal position of each sampling site. conifersIP has following variables:

• Year: year of tree-ring formation (1950-1999)

• Region: geographical region for Iberian Peninsula: north, centre, south

• Species: tree species: Abies alba, Pinus nigra, Pinus sylvestris

• Code: specific name of tree-ring width chronology

• TRW: residual indices of tree-ring width chronologies
