Pennsylvania Tree Ring Chronology from 525 to -28 BP

NOAA/WDS Paleoclimatology archives a tree ring chronology from the Tionesta Natural Area in Pennsylvania. The data provides a time series covering the period from 525 to -28 calendar years before present. NOAA National Centers for Environmental Information (NCEI) published this study, which was last updated in 1978.

Use Cases

• Reconstruct past climate variables like temperature or precipitation from the tree ring width series.
• Calibrate and validate climate models using the high-resolution, annually-dated proxy record.
• Analyze the frequency and magnitude of extreme climatic events within the 553-year chronology.
• Study forest growth responses to environmental changes over centuries at the Tionesta site.

Strengths

• Time series spans 553 calendar years (525 to -28 BP).
• Data is part of the authoritative NOAA/NCEI World Data Service for Paleoclimatology.

Limitations

• Data is temporally stale, with a last update recorded in 1978.
• Geographic coverage is limited to a single site in Pennsylvania.
