Finnish Pine Tree Ring Chronology from 267 to 34 BC

Tree ring width measurements from Scots pine (PISY) in Lieksa Patvinsuo, Finland, provide a 301-year paleoclimate record. The dataset, archived by NOAA's World Data Service for Paleoclimatology, covers the period from 267 to 34 years before present. Data collection and publication were completed by researcher Eronen and the International Tree-Ring Data Bank.

Use Cases

• Reconstruct past temperature or precipitation anomalies by analyzing annual tree-ring width variations.
• Calibrate and extend regional dendrochronological master chronologies for Finland using the PISY species record.
• Study ecological responses to historical climate events by examining growth suppression or release patterns in the ring series.
• Validate climate model simulations for the late Holocene period with a high-resolution proxy record.

Strengths

• 301-year continuous chronology from 267 to 34 BC
• Data sourced from the authoritative NOAA/NCEI World Data Service for Paleoclimatology

Limitations

• Dataset is temporally stale, with a last update recorded in 1984
• Sample size and replication statistics are unknown from the provided metadata
