Finnish Tree-Ring Chronology from 372 to 33 BCE

405 years of tree-ring data from Finland and Scandinavia, covering the period from 372 to 33 BCE. The dataset is part of the NOAA/WDS Paleoclimatology archive, specifically the International Tree-Ring Data Bank (ITRDB) collection. It was contributed by researcher Briffa and last archived in 1983.

Use Cases

• Calibrating tree-ring width measurements against known climate proxies to reconstruct past temperatures for Finland.
• Analyzing the chronology for marker years (e.g., narrow rings) to identify volcanic eruption events or extreme drought periods in Scandinavia.
• Cross-dating this Finnish chronology (PISY) with other regional ITRDB series to validate and extend climate reconstructions.
• Investigating long-term growth trends in the tree-ring parameter to study ecological responses to environmental change over four centuries.

Strengths

• Covers a 405-year time period from 372 to 33 BCE.
• Geographically specific to Finland and Scandinavia.
• Archived within the authoritative NOAA/NCEI World Data Service for Paleoclimatology.

Limitations

• Data was last updated in 1983, potentially lacking modern reanalysis or calibration.
• The exact parameters, sample depth, and replication statistics are unknown from the provided description.
• Temporal coverage ends at 33 BCE, limiting analysis of more recent climate history.
