Finnish Tree Ring Chronology for Paleoclimate Reconstruction

Tree ring width measurements from the Palasjarvi Palastunturi site in Finland, used for climate reconstruction. The chronology covers a period from 168 to -28 calendar years before present. This archived study was published by the NOAA National Centers for Environmental Information in 1978.

Use Cases

• Reconstruct past temperature or precipitation anomalies using tree ring width as a proxy.
• Calibrate regional climate models by comparing the tree ring chronology with instrumental climate records.
• Analyze growth patterns and extreme events within the 196-year time series from the Palasjarvi site.
• Cross-date and validate other tree ring chronologies from the Scandinavian region using this reference series.

Strengths

• Chronology spans 196 calendar years, providing a multi-century climate record.
• Data is curated and archived by the authoritative NOAA World Data Service for Paleoclimatology.

Limitations

• Data is from a single site (Palasjarvi Palastunturi), limiting spatial representativeness.
• The dataset was last updated in 1978, and newer methodologies may not be reflected.
• Sample size and replication depth for individual years are unknown from the description.
