Spanish Tree-Ring Chronology from 283 to 38 BCE

Tree-ring width data from Spain provides a climate proxy record spanning 321 years from 283 to 38 BCE. The dataset is archived by NOAA's World Data Service for Paleoclimatology and was last updated in 1988. It originates from the Penahorcada - PINI site as part of the International Tree-Ring Data Bank.

Use Cases

• Reconstruct past temperature or precipitation anomalies in Southern Europe using annual tree-ring width as a proxy.
• Calibrate climate models by comparing simulated past conditions with the high-resolution time-series of tree-ring growth.
• Analyze the frequency and severity of historical drought events in Spain through patterns in the ring-width chronology.
• Cross-date and validate other paleoclimate archives from the Mediterranean region using this established tree-ring series.

Strengths

• 321-year continuous annual chronology from 283 to 38 BCE.
• Data is curated and archived by the authoritative NOAA World Data Service for Paleoclimatology.
• Part of the standardized International Tree-Ring Data Bank (ITRDB) collection.

Limitations

• The dataset is temporally stale, with no updates since its publication in 1988.
• Geographic coverage is limited to a single site (Penahorcada - PINI) in Spain.
• Specific measurement parameters and sample depth (number of trees) are unknown from the provided description.
