资源简介：
Across seven sites in southern Utah and northern Arizona, we collected precipitation, xylem water, and soil water isotope samples during two years: 2018 and 2021. All xylem water samples were collected from mature Ponderosa pine forests. At each site, xylem water samples were collected from the same 15 trees during two periods during 2018, and three periods during 2021. Soil pits were dug close to the trees and soil samples were collected at 5, 25, and 45cm depth close to the tree xylem samples. In 2021, we also collected precipitation isotopes using a rain gauge that was topped with mineral oil to prevent evaporation.
