Ponderosa Pine Pith Offsets Corresponding to gp.rwl
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.

that series in

pith.offset). This can be used together with the ring
widths to calculate the cambial age of each ring.
