Colorado Ponderosa Pine Tree Ring Chronology From 137 BC

NOAA/WDS Paleoclimatology archives a tree-ring dataset from the Schweingruber - Wheelman - PIPO study, part of the International Tree-Ring Data Bank (ITRDB). The data provides a chronology for Ponderosa Pine (PIPO) in Colorado, USA, covering the period from 137 to -32 calendar years before present. This archived study was contributed by NOAA National Centers for Environmental Information (NCEI) and was last updated in 1982.

Use Cases

• Reconstruct past temperature or precipitation anomalies using annual tree-ring width measurements.
• Calibrate climate proxy models by correlating ring-width indices with known historical climate events.
• Analyze growth response patterns to environmental stressors documented in the site chronology.
• Validate regional climate reconstructions by comparing this Ponderosa Pine chronology with other ITRDB records.

Strengths

• Chronology spans 169 years (137 to -32 BP), providing a multi-century climate proxy.
• Data is curated and archived by the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• The dataset's last update was in 1982, potentially missing modern verification or methodological improvements.
• Specific sample size, measurement parameters, and replication statistics are not provided in the input.
