Spanish Tree-Ring Chronology from 263 to -39 Years Before Present

Tree-ring width measurements from Spain provide a proxy climate record spanning 302 years, from 263 to -39 calendar years before present. The dataset is archived by NOAA's National Centers for Environmental Information under its World Data Service for Paleoclimatology. This specific chronology was last updated in 1989.

Use Cases

• Reconstruct past temperature or precipitation anomalies in Southern Europe by calibrating tree-ring width series against instrumental records.
• Analyze the frequency and severity of historical drought events by identifying narrow ring sequences within the chronology.
• Cross-date and validate other tree-ring chronologies from the Mediterranean region using this series as a reference.
• Study long-term forest growth trends and responses to environmental stressors using the annual resolution of ring-width data.

Strengths

• Covers a 302-year period, providing a multi-century climate proxy.
• Sourced from the authoritative NOAA/NCEI World Data Service for Paleoclimatology.

Limitations

• The chronology ends 39 years before present (1950 CE), lacking modern climate context.
• Data last updated in 1989, potentially missing newer methodological refinements.
• Specific sample depth, geographic precision, and measurement parameters are unknown from the description.
