Tree-ring carbon isotope data and drought maps
for the U.S. Southwest


The Data
Appendix A. Original δ13C Data and Isotope Drought Indices for Each Site

1. Pentad δ13C isotope values, 1490-94 to 1985-89
2. Pentad Isotope Drought Indices, 1600-04 to 1995-99,
where the 1985-89, 1990-94 and 1995-99 pentads are derived from a spline fit
3. Pentad Isotope Drought Indices, 1600-04 to 1995-99,
where the 1985-89, 1990-94 and 1995-99 pentads are derived from averages
of the single-year Isotope Drought Indices
4. Single-yr Isotope Drought Indices, 1985-2001
