Tree ring width measurements from Ilomantsi Tasanenkangas, Finland, provide a 199-year chronology for environmental reconstruction. The data covers the period from 166 to -33 calendar years before present. This archived study was published by NOAA NCEI's World Data Service for Paleoclimatology in 1983.
Use Cases
- Reconstruct past temperature or precipitation anomalies using tree ring width as a proxy.
- Calibrate regional climate models by comparing the chronology with known historical climate events.
- Analyze growth patterns to infer environmental stress events within the 199-year time series.
- Cross-date archaeological wood samples from Finland using this established master chronology.
Strengths
- 199-year continuous chronology from 166 to -33 BP.
- Data is archived and curated by NOAA's authoritative World Data Service for Paleoclimatology.
Limitations
- Data is temporally stale, last updated in 1983, potentially missing modern analytical techniques.
- Geographic coverage is limited to a single site in Finland, limiting broader regional analysis.
- Specific sample depth, measurement parameters, and potential error ranges are not detailed in the provided metadata.
