Santa Rita Mountains Tree Ring Chronology from 350 to -36 BP

Arizona tree ring data from the Santa Rita Mountains, covering the period from 350 to -36 calendar years before present. This paleoclimatology study contains parameters related to tree growth, specifically from the PSME (Pinus strobiformis) species. The dataset is archived by NOAA's National Centers for Environmental Information under the World Data Service for Paleoclimatology.

Use Cases

• Reconstructing past climate variables like precipitation or temperature from annual tree-ring width measurements.
• Calibrating radiocarbon dating or other chronological models using the dated tree-ring series.
• Analyzing long-term growth trends and stress events in Pinus strobiformis (PSME) for ecological studies.
• Cross-dating this chronology (ITRDB AZ544) with other regional tree-ring datasets to validate climate signals.

Strengths

• Temporal coverage spans 386 years, from 350 to -36 calendar years BP.
• Data is part of the authoritative International Tree-Ring Data Bank (ITRDB) collection.

Limitations

• The dataset's last update was in 1986, indicating it is a static, historical archive.
• Specific parameters, sample depth, and measurement methodologies are not detailed in the provided description.
• Geographic coverage is limited to a single site in the Santa Rita Mountains of Arizona.
