Ponderosa Pine Pith Offsets Corresponding to gp.rwl
Description
This data set gives the pith offsets that match 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
data(gp.po)
Format
A data.frame containing series IDs in column 1
(series) and the number of years between the beginning of
that series in gp.rwl and the pith of the tree
(pith.offset). This can be used together with the ring
widths to calculate the cambial age of each ring.
