Spanish Tree Ring Chronology from 345 to -35 BP

A 380-year tree ring chronology from the Hecho Puerto de Acher site in Spain, covering the period from 345 to -35 calendar years before present. This paleoclimatology study is provided by the NOAA National Centers for Environmental Information under the World Data Service for Paleoclimatology. The data was archived and last updated in 1985.

Use Cases

• Reconstruct past temperature or precipitation anomalies by analyzing the annual tree-ring width series.
• Calibrate the chronology against other regional proxy records using the documented calendar year timeline.
• Study the frequency of extreme climatic events indicated by narrow or wide ring sequences in the time series.

Strengths

• Covers a continuous 380-year period (345 to -35 BP) for climate analysis.
• Sourced from the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• The dataset is temporally stale, with a last update date of 1985, potentially lacking modern reanalysis.
• Sample size, geographic representativeness, and specific measurement parameters are unknown from the provided metadata.
