Finnish Tree Ring Chronology from 341 to 130 BC

Tree ring data from the Ilomantsi Sissola site in Finland, covering a 211-year period from 341 to 130 BC. The dataset is archived by the NOAA National Centers for Environmental Information under its Paleoclimatology program. It is associated with the International Tree-Ring Data Bank series FINL051.

Use Cases

• Reconstruct historical climate variables like temperature or precipitation using tree ring width measurements.
• Calibrate and validate climate models for the Scandinavian region using the 211-year chronology.
• Analyze growth patterns of Scots pine (PISY) in Finland during the pre-Roman Iron Age.
• Cross-date this chronology (ITRDB FINL051) with other regional tree ring series to build longer climate records.

Strengths

• Covers a specific 211-year period (341 to 130 BC) for clear temporal analysis.
• Sourced from the authoritative NOAA NCEI World Data Service for Paleoclimatology.
• Part of the standardized International Tree-Ring Data Bank (ITRDB) collection.

Limitations

• Temporal coverage is limited to a single 211-year slice of history.
• Geographic scope is restricted to one site (Ilomantsi Sissola) in Finland.
• The dataset's last known update date is 1820, indicating metadata may be stale.
