French Oak Tree Ring Chronology from 231 to 29 BCE

260-year tree ring chronology from oak trees in the Foret d'Halatte, Oise, France, covering the period from 231 to 29 calendar years before present. The dataset is part of the NOAA/WDS Paleoclimatology archive and was published by the NOAA National Centers for Environmental Information. The data was last updated in the archive in 1979.

Use Cases

• Reconstruct past temperature or precipitation patterns for Oise, France, using the annual tree-ring width series.
• Calibrate radiocarbon dating for the late Iron Age/Roman period in France using the precisely dated tree-ring chronology.
• Analyze forest growth responses to historical environmental events recorded in the ring-width parameter.
• Compare this local chronology with other European tree-ring datasets to study regional climate teleconnections.

Strengths

• Covers a 260-year period from 231 to 29 BCE, providing a continuous annual record.
• Sourced from the authoritative NOAA/WDS Paleoclimatology archive and associated with the ITRDB (International Tree-Ring Data Bank).

Limitations

• The dataset is temporally stale, with a last updated date of 1979, indicating it may not reflect modern analytical methods.
• Limited geographic scope to a single forest (Foret d'Halatte) in France, reducing broad regional applicability.
• The raw sample size (number of tree cores) and specific measurement parameters beyond 'tree ring' are unknown from the description.
