Swedish Pine Tree Ring Chronology from 823 to 37 BC

860 years of tree-ring width measurements from Scots Pine trees on Gotland, Sweden, used to reconstruct past climate. The dataset was archived by the NOAA National Centers for Environmental Information under its World Data Service for Paleoclimatology. The original study was published in 1987.

Use Cases

• Calibrating tree-ring width as a temperature or precipitation proxy for Scandinavian climate models.
• Cross-dating the 860-year chronology against other regional tree-ring series to validate temporal accuracy.
• Analyzing growth anomaly years within the series to identify extreme historical climate events.
• Reconstructing summer temperature or drought indices for the Baltic region over the 8th to 1st centuries BC.

Strengths

• Covers 860 consecutive years from 823 to 37 BC, providing a long-term baseline.
• Data is curated and archived by the authoritative NOAA World Data Service for Paleoclimatology.

Limitations

• The dataset is temporally stale, with no updates since its original publication in 1987.
• Geographic coverage is limited to a single island (Gotland), which may not represent broader regional patterns.
• Specific sample depth, measurement statistics, and potential missing years are not detailed in the provided metadata.
