gp.d2pith: Ponderosa Pine Distance to Pith Corresponding to 'gp.rwl'

Description Usage Format Source References

Description

This data set gives the distance to pith for each series (in mm) that matches the ring widths for gp.rwl – a data set of ponderosa pine (Pinus ponderosa) from the Gus Pearson Natural Area (GPNA) in northern Arizona, USA. Data are further described by Biondi and Qeadan (2008) and references therein.

Usage

1

Format

A data.frame containing series IDs in column 1 (series) and the distance (in mm) from the innermost ring to the pith of the tree (d2pith). This can be used together with the ring widths to calculate the area of each ring.
