Schweingruber Tree Ring Chronology from Central Spain

NOAA/WDS Paleoclimatology archives a tree-ring chronology from the Calvero site in Spain's Sierra de Gredos. The data provides a 54-year time series for paleoclimate reconstruction, centered around 27 years before present. This dataset was published by the NOAA National Centers for Environmental Information in 1977.

Use Cases

• Reconstruct past climate conditions using tree-ring width parameters as a proxy for temperature or precipitation.
• Calibrate regional climate models by comparing the tree-ring chronology time series with instrumental records.
• Analyze growth anomaly patterns within the 54-year series to identify extreme historical climate events.
• Perform cross-dating with other Iberian Peninsula tree-ring chronologies to validate regional climate signals.

Strengths

• Data is curated and archived by the authoritative NOAA National Centers for Environmental Information.
• Provides a precisely dated 54-year tree-ring chronology (from 27 to -27 BP).
• Geographic location is specified to a site in Spain, Southern Europe.

Limitations

• The dataset is temporally limited, covering only 54 years of proxy data.
• Data is geographically narrow, sourced from a single site (Calvero, Sierra de Gredos).
• The dataset is stale, with a last documented update in 1977, potentially lacking modern methodological refinements.
