Spanish Tree Ring Chronology From 341 to 27 BCE

368 calendar years of tree-ring data from Spain, covering the period from 341 to 27 BCE. The dataset was archived by NOAA's World Data Service for Paleoclimatology as part of the Schweingruber collection. It was last updated in the NOAA system in 1977.

Use Cases

• Reconstruct past temperature or precipitation anomalies using the tree-ring width chronology.
• Calibrate radiocarbon dating sequences for Southern Europe using the dated tree-ring series.
• Analyze climate forcing events like volcanic eruptions by identifying narrow rings in the chronology.
• Compare this Iberian Peninsula chronology with other ITRDB records to study regional climate teleconnections.

Strengths

• Covers 368 years of calibrated time from 341 to 27 BCE.
• Geographically specific to Spain in Southern Europe.

Limitations

• Temporal coverage ends at 27 BCE, lacking overlap with more recent historical periods.
• The data's last known update was in 1977, potentially using outdated collection or calibration methods.
• Sample size and replication depth of the underlying tree cores are unknown.
