Spanish Tree Ring Chronology from 269 to 34 BC

Tree ring width measurements from the Gudar Fuentenarices site in Spain, used for paleoclimate reconstruction. Data coverage spans 303 years, from 269 to 34 BC. The dataset was archived by NOAA's National Centers for Environmental Information.

Use Cases

• Reconstruct past temperature or precipitation anomalies using annual tree ring width as a proxy.
• Calibrate climate models by comparing the tree ring chronology with simulated climate data for the period 269-34 BC.
• Analyze growth trends and extreme climate events within the 303-year time series from the Gudar Fuentenarices site.

Strengths

• Time series spans 303 calendar years (269 to 34 BC).
• Data is curated and archived by the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• Dataset is temporally stale, with a last update recorded in 1984.
• Sample size and replication level (number of tree cores) are unknown, limiting statistical confidence.
• Geographic coverage is limited to a single site in Spain, reducing regional representativeness.
