NOAA/WDS Paleoclimatology archives a tree ring dataset from Oulanka National Park, Finland. The chronology covers 252 calendar years, from 224 to -28 years before present. The data was published by the NOAA National Centers for Environmental Information in 1978.
Use Cases
- Reconstruct past temperature or precipitation using the tree ring width chronology as a climate proxy.
- Calibrate radiocarbon dating models by cross-referencing the dated tree ring series.
- Analyze growth patterns and environmental stress events recorded in the ring parameters.
Strengths
- Data spans a 252-year chronology from 224 to -28 years BP.
- Curated and archived by the authoritative NOAA National Centers for Environmental Information.
Limitations
- Temporal coverage is limited to a specific 252-year period, not continuous to present.
- Sample size and replication details for the tree ring series are unknown.
- Data is temporally stale, with a last documented update in 1978.
