Oklahoma Tree Ring Chronology from Canadian River Basin

NOAA NCEI archives a tree-ring chronology from the Canadian River area in Oklahoma, United States. The data covers a period from 270 to -32 calendar years before present, indicating a span crossing the year zero. This paleoclimatology study was published by the NOAA National Centers for Environmental Information in 1982.

Use Cases

• Reconstruct past temperature or precipitation for Oklahoma using the tree-ring width chronology.
• Calibrate climate models by comparing the tree-ring proxy data with known historical climate events.
• Analyze long-term climate trends and variability in the Southern Plains from the 3rd century BC to the 1st century AD.
• Cross-date archaeological wood samples from the region using the established tree-ring chronology.

Strengths

• Data spans approximately 302 years (from 270 to -32 BP), providing a multi-century climate record.
• Sourced from the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• Temporal coverage ends at -32 BP (approximately 1982 CE), with no updates since the original 1982 publication.
• Geographic scope is limited to a single site in Oklahoma, limiting regional representativeness.
• Specific parameters (e.g., ring-width, density) and sample depth are not detailed in the provided metadata.
