Polish Tree-Ring Chronology from Hajnowka (230 to -35 BP)

NOAA NCEI archives a tree-ring chronology from Hajnowka, Poland, covering a 265-year period from 230 to -35 calendar years before present. The dataset contains parameters related to tree-ring growth, used for reconstructing past environmental conditions. It was published by the NOAA National Centers for Environmental Information under the World Data Service for Paleoclimatology.

Use Cases

• Calibrating regional climate models using the tree-ring width time-series as a proxy for past temperature or precipitation.
• Analyzing growth anomaly years within the 265-year chronology to identify extreme historical climate events in Poland.
• Cross-dating archaeological wood samples from Eastern Europe against the Hajnowka master chronology for dating purposes.

Strengths

• Covers a continuous 265-year period from 230 to -35 BP, providing a multi-century baseline.
• Sourced from the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• Temporal coverage is relatively short (265 years) compared to other millennial-length tree-ring chronologies.
• Data was last updated in 1985, potentially lacking modern reanalysis or updated metadata.
