Irish Tree Ring Chronology from Lough Doon (100-28 BC)

NOAA/WDS Paleoclimatology archives a tree ring chronology from Lough Doon, Ireland. The dataset provides parameters for dendrochronological analysis covering the period from 100 to -28 calendar years before present. NOAA National Centers for Environmental Information (NCEI) maintains this study, which was last updated in 1978.

Use Cases

• Reconstruct past temperature or precipitation anomalies using the tree ring width parameter as a climate proxy.
• Cross-date archaeological wood samples from Ireland by matching patterns in the ring width chronology.
• Analyze long-term environmental stress events recorded in the tree ring parameters for the specified geographic location.
• Calibrate radiocarbon dating curves for the 100-28 BC period using the precisely dated tree ring series.

Strengths

• Covers a 128-year period (100 to -28 BP), providing a continuous environmental record.
• Sourced from the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• Temporal coverage is limited to a specific 128-year window in the late Iron Age.
• Data was last updated in 1978, indicating potential methodological staleness.
• Specific parameters, sample depth, and measurement details are not provided in the basic description.
