French Tree Ring Chronology from Pic Aubas (166 to -27 BP)

193 calendar years of tree ring data from the Pic Aubas site in France, covering the period from 166 to -27 years before present. This paleoclimatology study was archived by NOAA's National Centers for Environmental Information under the World Data Service. The dataset was last updated in the NOAA system in 1977.

Use Cases

• Calibrate regional climate models using the tree ring width chronology as a proxy for past temperature or precipitation.
• Analyze growth anomaly patterns within the 193-year chronology to identify extreme climatic events like droughts.
• Cross-date and validate other European tree ring series using the established Pic Aubas chronology.
• Study long-term forest growth trends in Western Europe from the ring width measurements.

Strengths

• Covers 193 calendar years of environmental history.
• Geographically specific to a single site in France, Western Europe.
• Part of the authoritative NOAA/NCEI World Data Service for Paleoclimatology.

Limitations

• Temporal coverage ends 27 years before present, limiting analysis of very recent climate.
• Sample size and replication statistics for the tree ring series are unknown.
• Data last updated in 1977, potentially lacking modern reanalysis or metadata enhancements.
