S P Mountain Tree Ring Chronology for Paleoclimate Reconstruction

NOAA/WDS Paleoclimatology archives a tree ring chronology dataset from the S P Mountain site in Arizona. The data cover a period from 261 to -22 calendar years before present (BP), representing a 283-year sequence. This study is maintained by the NOAA National Centers for Environmental Information under its World Data Service.

Use Cases

• Calibrating climate models by comparing tree ring width chronologies against instrumental climate records.
• Reconstructing past drought severity and frequency in Arizona from annual tree ring growth parameters.
• Analyzing long-term vegetation response to climate change using the dated tree ring series.

Strengths

• Data spans a 283-year period (261 to -22 BP), providing a multi-century climate proxy.
• Archived and curated by the authoritative NOAA National Centers for Environmental Information.

Limitations

• Temporal coverage ends at -22 BP (1972 CE), lacking recent decades for contemporary climate analysis.
• Specific sample depth, measurement parameters, and site details are not provided in the basic metadata.
