What information about monsoons and inter-seasonal precipitation is recorded in tree rings?

​In a collaborative project with Russ Monson and colleagues at the Tree Ring Lab at the University of Arizona, the Bill Anderegg and Ehleringer Labs at Utah are investigating oxygen isotope ratio variations in tree rings.

The project focuses on (a) understanding needle water isotope enrichment, (b) isotope/xylogenesis data observations and modeling along monsoonal gradients in the southwestern US, (c) modeling primary productivity of ponderosa pine along monsoonal gradients,  and (d) temporal/spatial modeling of tree ring isotopes.

Steve Kannenberg and Rich Fiorella are postdocs for this project.
