Tree ring width measurements from Ferne Clyffe State Park in Illinois provide a 326-year climate proxy record. The data covers the period from 295 to -31 calendar years before present, created by Duvick and archived by NOAA's World Data Service for Paleoclimatology. This study was last updated in 1981.
Use Cases
- Reconstruct historical temperature or precipitation patterns from tree ring width series.
- Calibrate climate models using the 326-year proxy record for the Illinois region.
- Analyze growth anomalies in the ring width data to identify past drought or extreme climate events.
- Cross-date this chronology with other regional tree ring datasets to validate temporal coverage.
Strengths
- 326-year temporal coverage from 295 to -31 BP
- Data is curated and archived by NOAA's authoritative World Data Service for Paleoclimatology
Limitations
- Data is temporally stale, last updated in 1981
- Geographic scope is limited to a single state park in Illinois
- Sample size and replication level are unknown
