149 to -28 calendar years before present of tree ring width measurements for climate reconstruction. The dataset is part of the NOAA NCEI Paleoclimatology archive, contributed by Schweingruber and associated with the International Tree-Ring Data Bank. It was archived in 1978.
Use Cases
- Reconstruct past temperature or precipitation anomalies using tree ring width as a proxy.
- Calibrate radiocarbon dating or other chronological models using the dated tree ring series.
- Analyze climate extremes and events like volcanic eruptions or droughts within the 177-year period covered.
- Compare this Finnish site chronology with other ITRDB series to study regional climate patterns.
Strengths
- Covers a 177-year period from 149 to -28 BP, providing a multi-century climate record.
- Part of the authoritative International Tree-Ring Data Bank (ITRDB) and NOAA WDS for Paleoclimatology.
Limitations
- Data is temporally stale, last updated in 1978, potentially lacking modern reanalysis or corrections.
- Geographic coverage is limited to a single site in Kyynara National Park, Finland.
