Tennessee Tree Ring Chronology from 267 to -47 BP

NOAA/WDS Paleoclimatology archives a tree ring chronology dataset from the Lynn Hollow and Look Rock Trail sites in Tennessee. The data provides annual-resolution climate proxy records covering the period from 267 to -47 calendar years before present. This study is maintained by the NOAA National Centers for Environmental Information.

Use Cases

• Reconstruct past temperature or precipitation anomalies using the annual tree-ring width series.
• Calibrate climate models by comparing the tree-ring chronology with other regional paleoclimate proxies.
• Analyze long-term ecological trends and forest growth responses captured in the ring parameters.
• Study the frequency of extreme climatic events, such as droughts, recorded in the ring sequences.

Strengths

• Data spans a significant period of 314 years (from 267 to -47 BP).
• Sourced from the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• Dataset is temporally stale, with a last documented update in 1997.
• Specific parameters, sample depth, and measurement methodologies are not detailed in the provided description.
