Pennsylvania Tree Ring Chronology from 309 to 31 BCE

340-year tree ring chronology from Bear Run, Pennsylvania, spanning 309 to 31 calendar years before present. The data, archived as a Paleoclimatology Study, was published by NOAA National Centers for Environmental Information under the World Data Service for Paleoclimatology. The record was last updated in the NOAA system in 1981.

Use Cases

• Reconstruct past climate variables like temperature or precipitation by analyzing the tree-ring width time-series.
• Calibrate and validate climate models using the 340-year proxy record from Pennsylvania.
• Study forest growth responses to historical environmental events documented in the ring chronology.
• Perform cross-dating with other regional tree-ring records to build a longer climate history.

Strengths

• Provides a 340-year continuous proxy record for climate analysis.
• Data is curated and archived by the authoritative NOAA World Data Service for Paleoclimatology.

Limitations

• Temporal coverage ends in 31 BCE, offering no data for the modern era.
• Geographic scope is limited to a single site (Bear Run, Pennsylvania).
• The underlying data collection and methodology details are not provided in the available description.
