piru13C

Accompanying tree ring carbon isotope signature data for "Mathias, J.M. &amp; Thomas, R.B. Disentangling the effects of acidic air pollution, atmospheric CO2, and climate change
on recent growth of red spruce trees in the Central Appalachian Mountains. Glob. Chang. Biol. 24, 3938–3953 (2018).".

datasets

Perform common calculations based on published stable isotope theory, such as calculating carbon isotope discrimination and intrinsic water use efficiency from wood or leaf carbon isotope composition. See Mathias and Hudiburg (2022) in Global Change Biology <doi:10.1111/gcb.16407>.
