Irish Tree Ring Chronology from 139 to -28 BP

A 167-year tree ring chronology from Enniscorthy, Ireland, provides data for paleoclimate reconstruction. The dataset is archived by NOAA's World Data Service for Paleoclimatology and was published in 1978. It captures tree ring parameters from the British Isles.

Use Cases

• Reconstruct past climate variables like temperature or precipitation using annual tree ring width measurements.
• Calibrate and validate climate models for the British Isles region using the 167-year proxy record.
• Analyze growth anomalies in the tree ring series to identify extreme historical climate events.
• Establish a regional dendrochronological master chronology for cross-dating other Irish tree ring samples.

Strengths

• Covers a specific 167-year period from 139 to -28 calendar years before present.
• Sourced from the authoritative NOAA/NCEI World Data Service for Paleoclimatology.
• Provides a geographically specific record for Ireland, a key region for North Atlantic climate studies.

Limitations

• Temporal coverage is relatively short (167 years) for long-term climate trend analysis.
• Data is geographically limited to a single site (Enniscorthy), reducing regional representativeness.
• The dataset is temporally stale, with a last update date of 1978, indicating older collection and analysis methods.
