Irish Oak Tree Ring Chronology from 141 to -28 BP

Tree ring width chronology from the Glen of the Downs site in Ireland provides a 169-year climate proxy record. Data coverage spans from 141 to -28 calendar years before present, with negative years indicating dates after 1950 CE. This archived study is maintained by NOAA's National Centers for Environmental Information under the World Data Service for Paleoclimatology.

Use Cases

• Calibrating regional climate models using the 169-year tree ring width series as a temperature/moisture proxy.
• Cross-dating archaeological wood samples from Ireland by matching patterns in the Glen of the Downs chronology.
• Analyzing climate anomalies in the 1st-2nd century BCE Ireland via annual ring width variations.

Strengths

• Temporal coverage is precisely defined from 141 to -28 calendar years BP.
• Data is archived and curated by the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• Dataset is small, containing a single chronology series for one site.
• Data is temporally stale, with a last update date recorded in 1978.
• Geographic coverage is limited to a single location (Glen of the Downs, Ireland).
