Porter Brook Tree Ring Chronology From 125 to -37 BP

Tree ring data from the Porter Brook site in the British Isles, United Kingdom, covering 162 years from 125 to -37 calendar years before present. The dataset is archived by NOAA's World Data Service for Paleoclimatology and is associated with a Tree Ring study type. The data was last updated in 1987.

Use Cases

• Calibrating regional climate models using the FREX (Fraxinus excelsior) tree ring width chronology.
• Analyzing growth anomalies in the ITRDB BRIT032 series to infer past drought or temperature events.
• Cross-dating the Porter Brook chronology with other European tree ring records to validate historical timelines.

Strengths

• 162-year chronology provides a continuous environmental record.
• Data is curated and archived by the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• Dataset is temporally stale, last updated in 1987.
• Limited geographic scope to a single site (Porter Brook) in the British Isles.
• Unknown sample size and replication depth for the tree ring series.
