Tree ring data from Illinois spans 241 years, from 226 to -15 calendar years before present. The National Oceanic and Atmospheric Administration's National Centers for Environmental Information archives this paleoclimatology study. The record was last updated in 1965.
Use Cases
- Reconstruct annual temperature or precipitation anomalies from tree ring width measurements.
- Calibrate the chronology against other proxy records using the provided calendar year BP time index.
- Analyze growth patterns and climate sensitivity for the specific tree species at the Pine Hills site.
Strengths
- 241-year continuous chronology provides multi-century context.
- Data is curated and archived by the authoritative NOAA World Data Service for Paleoclimatology.
Limitations
- The dataset's last update was in 1965, potentially missing modern analytical refinements.
- Geographic coverage is limited to a single site in Illinois, limiting regional representativeness.
