Tennessee Tree Ring Chronology For Climate Reconstruction

Tree ring width measurements from the Hen Wallow Falls B site in Tennessee, USA, used for paleoclimate analysis. The chronology covers 202 years, from 157 to -45 calendar years before present. This archived dataset is provided by NOAA's National Centers for Environmental Information under its World Data Service for Paleoclimatology.

Use Cases

• Reconstruct past temperature or precipitation anomalies in Tennessee by calibrating tree ring width series against modern instrumental records.
• Analyze the frequency and severity of historical drought events in the region by identifying narrow ring sequences in the chronology.
• Cross-date archaeological wood samples from the southeastern US by matching their ring patterns against this master chronology.
• Study forest growth responses to climate over a 202-year period using the annual resolution of the ring width data.

Strengths

• Covers a 202-year time period (157 to -45 BP) providing a multi-century climate proxy.
• Data is archived and curated by NOAA's authoritative World Data Service for Paleoclimatology.

Limitations

• Dataset is temporally stale, with a last recorded update in 1995, potentially lacking modern methodological refinements.
• Geographic scope is limited to a single site (Hen Wallow Falls B) in Tennessee, limiting regional representativeness.
• Specific sample depth, measurement statistics, and potential missing years within the chronology are unknown from the provided metadata.
