122 calendar years of tree-ring data, from 81 to -41 years before present, provide a proxy record for past climate conditions. The dataset is part of the NOAA/WDS Paleoclimatology archive, specifically the ITRDB collection, and was last updated in 1991. It contains parameters derived from tree rings collected in Illinois, United States.
Use Cases
- Reconstruct past temperature or precipitation anomalies by analyzing the tree-ring width chronology.
- Calibrate climate models using the 122-year proxy record of environmental conditions.
- Study local environmental stressors by examining patterns in the ring-width parameter series.
- Perform cross-dating with other regional chronologies using the indexed tree-ring data.
Strengths
- Covers a specific 122-year time period (81 to -41 BP) for climate analysis.
- Part of the authoritative NOAA/WDS Paleoclimatology and ITRDB archives.
Limitations
- Data is temporally stale, with a last update recorded in 1991.
- The geographic scope is limited to a single site in Illinois, reducing regional generalizability.
- Unknown sample size (number of trees/cores) limits assessment of statistical robustness.
