Oklahoma Tree Ring Chronology From 265 BC

Tree ring data from McCurtain County, Oklahoma, covering a 297-year period from 265 to 32 BC. The dataset is archived by the NOAA National Centers for Environmental Information under the World Data Service for Paleoclimatology. It was last updated in 1982.

Use Cases

• Reconstruct past climate variables like precipitation from annual tree ring width measurements.
• Calibrate and validate climate models using a precisely dated proxy record from 265-32 BC.
• Analyze long-term ecological growth patterns and responses to environmental stressors in Oklahoma's historical forests.

Strengths

• Covers a 297-year period, providing a multi-century climate proxy.
• Sourced from the authoritative NOAA/NCEI World Data Service for Paleoclimatology.

Limitations

• Temporal coverage ends 32 BC, lacking recent historical or modern data.
• Geographic scope is limited to a single county in Oklahoma.
• Data was last updated in 1982, indicating potential staleness in metadata or methods.
